After calling this method, and until there is a backtrack that undoes the addition, any assignment of variables to values must satisfy the given constraint in order to be considered feasible. There are two fairly different use cases: - the most common use case is modeling: the given constraint is really part of the problem that the user is trying to solve. In this use case, AddConstraint is called outside of search (i.e., with state() == OUTSIDE_SEARCH). Most users should only use AddConstraint in this way. In this case, the constraint will belong to the model forever: it cannot not be removed by backtracking. - a rarer use case is that 'c' is not a real constraint of the model. It may be a constraint generated by a branching decision (a constraint whose goal is to restrict the search space), a symmetry breaking constraint (a constraint that does restrict the search space, but in a way that cannot have an impact on the quality of the solutions in the subtree), or an inferred constraint that, while having no semantic value to the model (it does not restrict the set of solutions), is worth having because we believe it may strengthen the propagation. In these cases, it happens that the constraint is added during the search (i.e., with state() == IN_SEARCH or state() == IN_ROOT_NODE). When a constraint is added during a search, it applies only to the subtree of the search tree rooted at the current node, and will be automatically removed by backtracking. This method does not take ownership of the constraint. If the constraint has been created by any factory method (Solver::MakeXXX), it will automatically be deleted.

The main difference w.r.t a standard FIFO structure is that a Solver is given as parameter to the modifiers such that the solver can store the backtrack information Iterator's traversing order should not be changed, as some algorithm depend on it to be consistent. It's main use is to store a list of demons in the various classes of variables. The base class for all local search operators. A local search operator is an object that defines the neighborhood of a solution. In other words, a neighborhood is the set of solutions which can be reached from a given solution using an operator. The behavior of the LocalSearchOperator class is similar to iterators. The operator is synchronized with an assignment (gives the current values of the variables); this is done in the Start() method. Then one can iterate over the neighbors using the MakeNextNeighbor method. This method returns an assignment which represents the incremental changes to the current solution. It also returns a second assignment representing the changes to the last solution defined by the neighborhood operator; this assignment is empty if the neighborhood operator cannot track this information."""

Two nodes with hard incompatible types cannot be served by the same vehicle at all, while with a temporal incompatibility they can't be on the same route at the same time. The VisitTypePolicy of a node determines how visiting it impacts the type count on the route. For example, for - three temporally incompatible types T1 T2 and T3 - 2 pairs of nodes a1/r1 and a2/r2 of type T1 and T2 respectively, with     - a1 and a2 of VisitTypePolicy TYPE_ADDED_TO_VEHICLE     - r1 and r2 of policy ADDED_TYPE_REMOVED_FROM_VEHICLE - 3 nodes A, UV and AR of type T3, respectively with type policies   TYPE_ADDED_TO_VEHICLE, TYPE_ON_VEHICLE_UP_TO_VISIT and   TYPE_SIMULTANEOUSLY_ADDED_AND_REMOVED the configurations UV --> a1 --> r1 --> a2 --> r2,   a1 --> r1 --> a2 --> r2 --> A and a1 --> r1 --> AR --> a2 --> r2 are acceptable, whereas the configurations a1 --> a2 --> r1 --> ..., or A --> a1 --> r1 --> ..., or a1 --> r1 --> UV --> ... are not feasible. It also verifies same-vehicle and temporal type requirements. A node of type T_d with a same-vehicle requirement for type T_r needs to be served by the same vehicle as a node of type T_r. Temporal requirements, on the other hand, can take effect either when the dependent type is being added to the route or when it's removed from it, which is determined by the dependent node's VisitTypePolicy. In the above example: - If T3 is required on the same vehicle as T1, A, AR or UV must be on the   same vehicle as a1. - If T2 is required when adding T1, a2 must be visited *before* a1, and if   r2 is also visited on the route, it must be *after* a1, i.e. T2 must be on   the vehicle when a1 is visited:   ... --> a2 --> ... --> a1 --> ... --> r2 --> ... - If T3 is required when removing T1, T3 needs to be on the vehicle when   r1 is visited:   ... --> A --> ... --> r1 --> ...

BaseLns

class BaseLns (vars: std::vector< operations_research::IntVar * > const &)

Fragments are built with NextFragment(), which returns false if there are no more fragments to build. Optionally one can override InitFragments, which is called from LocalSearchOperator::Start to initialize fragment data.

Demon

class Demon

A Demon is the base element of a propagation queue. It is the main object responsible for implementing the actual propagation of the constraint and pruning the inconsistent values in the domains of the variables. The main concept is that demons are listeners that are attached to the variables and listen to their modifications. There are two methods: - Run() is the actual method called when the demon is processed. - priority() returns its priority. Standard priorities are slow, normal or fast. "immediate" is reserved for variables and is treated separately.

This indicates the priority of a demon. Immediate demons are treated separately and corresponds to variables.

IntVarIterator

class IntVarIterator (*args, **kwargs)

The class Iterator has two direct subclasses. HoleIterators iterates over all holes, that is value removed between the current min and max of the variable since the last time the variable was processed in the queue. DomainIterators iterates over all elements of the variable domain. Both iterators are not robust to domain changes. Hole iterators can also report values outside the current min and max of the variable. HoleIterators should only be called from a demon attached to the variable that has created this iterator. IntVar* current_var; std::unique_ptr it(current_var->MakeHoleIterator(false)); for (const int64 hole : InitAndGetValues(it)) { /// use the hole }

IntVarLocalSearchFilter

class IntVarLocalSearchFilter (vars: std::vector< operations_research::IntVar * > const &)

Local Search Filters are used for fast neighbor pruning. Filtering a move is done in several phases: - in the Relax phase, filters determine which parts of their internals will be changed by the candidate, and modify intermediary State - in the Accept phase, filters check that the candidate is feasible, - if the Accept phase succeeds, the solver may decide to trigger a Synchronize phase that makes filters change their internal representation to the last candidate, - otherwise (Accept fails or the solver does not want to synchronize), a Revert phase makes filters erase any intermediary State generated by the Relax and Accept phases. A given filter has phases called with the following pattern: (Relax.Accept.Synchronize | Relax.Accept.Revert | Relax.Revert)*. Filters's Revert() is always called in the reverse order their Accept() was called, to allow late filters to use state done/undone by early filters' Accept()/Revert().

LocalSearchFilter

class LocalSearchFilter (*args, **kwargs)

Local Search Filters are used for fast neighbor pruning. Filtering a move is done in several phases: - in the Relax phase, filters determine which parts of their internals will be changed by the candidate, and modify intermediary State - in the Accept phase, filters check that the candidate is feasible, - if the Accept phase succeeds, the solver may decide to trigger a Synchronize phase that makes filters change their internal representation to the last candidate, - otherwise (Accept fails or the solver does not want to synchronize), a Revert phase makes filters erase any intermediary State generated by the Relax and Accept phases. A given filter has phases called with the following pattern: (Relax.Accept.Synchronize | Relax.Accept.Revert | Relax.Revert)*. Filters's Revert() is always called in the reverse order their Accept() was called, to allow late filters to use state done/undone by early filters' Accept()/Revert().

LocalSearchOperator

class LocalSearchOperator (*args, **kwargs)

This class represent a reversible FIFO structure. The main difference w.r.t a standard FIFO structure is that a Solver is given as parameter to the modifiers such that the solver can store the backtrack information Iterator's traversing order should not be changed, as some algorithm depend on it to be consistent. It's main use is to store a list of demons in the various classes of variables. The base class for all local search operators. A local search operator is an object that defines the neighborhood of a solution. In other words, a neighborhood is the set of solutions which can be reached from a given solution using an operator. The behavior of the LocalSearchOperator class is similar to iterators. The operator is synchronized with an assignment (gives the current values of the variables); this is done in the Start() method. Then one can iterate over the neighbors using the MakeNextNeighbor method. This method returns an assignment which represents the incremental changes to the current solution. It also returns a second assignment representing the changes to the last solution defined by the neighborhood operator; this assignment is empty if the neighborhood operator cannot track this information.

PyConstraintDemon

class PyConstraintDemon (ct, method, delayed, *args)

A Demon is the base element of a propagation queue. It is the main object responsible for implementing the actual propagation of the constraint and pruning the inconsistent values in the domains of the variables. The main concept is that demons are listeners that are attached to the variables and listen to their modifications. There are two methods: - Run() is the actual method called when the demon is processed. - priority() returns its priority. Standard priorities are slow, normal or fast. "immediate" is reserved for variables and is treated separately.

This indicates the priority of a demon. Immediate demons are treated separately and corresponds to variables.

RoutingDimension

class RoutingDimension (*args, **kwargs)

Dimensions represent quantities accumulated at nodes along the routes. They represent quantities such as weights or volumes carried along the route, or distance or times. Quantities at a node are represented by "cumul" variables and the increase or decrease of quantities between nodes are represented by "transit" variables. These variables are linked as follows: if j == next(i), cumuls(j) = cumuls(i) + transits(i) + slacks(i) + state_dependent_transits(i) where slack is a positive slack variable (can represent waiting times for a time dimension), and state_dependent_transits is a non-purely functional version of transits_. Favour transits over state_dependent_transits when possible, because purely functional callbacks allow more optimisations and make the model faster and easier to solve. for a given vehicle, it is passed as an external vector, it would be better to have this information here.

In this use case, AddConstraint is called outside of search (i.e., with state() == OUTSIDE_SEARCH). Most users should only use AddConstraint in this way. In this case, the constraint will belong to the model forever: it cannot not be removed by backtracking. - a rarer use case is that 'c' is not a real constraint of the model. It may be a constraint generated by a branching decision (a constraint whose goal is to restrict the search space), a symmetry breaking constraint (a constraint that does restrict the search space, but in a way that cannot have an impact on the quality of the solutions in the subtree), or an inferred constraint that, while having no semantic value to the model (it does not restrict the set of solutions), is worth having because we believe it may strengthen the propagation. In these cases, it happens that the constraint is added during the search (i.e., with state() == IN_SEARCH or state() == IN_ROOT_NODE). When a constraint is added during a search, it applies only to the subtree of the search tree rooted at the current node, and will be automatically removed by backtracking. This method does not take ownership of the constraint. If the constraint has been created by any factory method (Solver::MakeXXX), it will automatically be deleted.

CROSS

var CROSS

Operator which cross exchanges the starting chains of 2 paths, including exchanging the whole paths. First and last nodes are not moved. Possible neighbors for the paths 1 -> 2 -> 3 -> 4 -> 5 and 6 -> 7 -> 8 (where (1, 5) and (6, 8) are first and last nodes of the paths and can therefore not be moved): 1 -> [7] -> 3 -> 4 -> 5 6 -> [2] -> 8 1 -> [7] -> 4 -> 5 6 -> [2 -> 3] -> 8 1 -> [7] -> 5 6 -> [2 -> 3 -> 4] -> 8

DECREMENT

var DECREMENT

Operator which defines a neighborhood to decrement values. The behavior is the same as INCREMENT, except values are decremented instead of incremented.

DELAYED_PRIORITY

var DELAYED_PRIORITY

DELAYED_PRIORITY is the lowest priority: Demons will be processed after VAR_PRIORITY and NORMAL_PRIORITY demons.

EQ

var EQ

Move is accepted when the current objective value is in the interval objective.Min .. objective.Max.

EXCHANGE

var EXCHANGE

Operator which exchanges the positions of two nodes. Possible neighbors for the path 1 -> 2 -> 3 -> 4 -> 5 (where (1, 5) are first and last nodes of the path and can therefore not be moved): 1 -> [3] -> [2] -> 4 -> 5 1 -> [4] -> 3 -> [2] -> 5 1 -> 2 -> [4] -> [3] -> 5

EXTENDEDSWAPACTIVE

var EXTENDEDSWAPACTIVE

Operator which makes an inactive node active and an active one inactive. It is similar to SwapActiveOperator except that it tries to insert the inactive node in all possible positions instead of just the position of the node made inactive. Possible neighbors for the path 1 -> 2 -> 3 -> 4 with 5 inactive (where 1 and 4 are first and last nodes of the path) are: 1 -> [5] -> 3 -> 4 with 2 inactive 1 -> 3 -> [5] -> 4 with 2 inactive 1 -> [5] -> 2 -> 4 with 3 inactive 1 -> 2 -> [5] -> 4 with 3 inactive

FULLPATHLNS

var FULLPATHLNS

Operator which relaxes one entire path and all inactive nodes, thus defining num_paths neighbors.

GE

var GE

Move is accepted when the current objective value >= objective.Min.

INCREMENT

var INCREMENT

Operator which defines one neighbor per variable. Each neighbor tries to increment by one the value of the corresponding variable. When a new solution is found the neighborhood is rebuilt from scratch, i.e., tries to increment values in the variable order. Consider for instance variables x and y. x is incremented one by one to its max, and when it is not possible to increment x anymore, y is incremented once. If this is a solution, then next neighbor tries to increment x.

INTERVAL_DEFAULT

var INTERVAL_DEFAULT

The default is INTERVAL_SET_TIMES_FORWARD.

INTERVAL_SET_TIMES_BACKWARD

var INTERVAL_SET_TIMES_BACKWARD

Selects the variable with the highest ending time of all variables, and fixes the ending time to this highest values.

INTERVAL_SET_TIMES_FORWARD

var INTERVAL_SET_TIMES_FORWARD

Selects the variable with the lowest starting time of all variables, and fixes its starting time to this lowest value.

INTERVAL_SIMPLE

var INTERVAL_SIMPLE

The simple is INTERVAL_SET_TIMES_FORWARD.

INT_VALUE_DEFAULT

var INT_VALUE_DEFAULT

The default behavior is ASSIGN_MIN_VALUE.

INT_VALUE_SIMPLE

var INT_VALUE_SIMPLE

The simple selection is ASSIGN_MIN_VALUE.

INT_VAR_DEFAULT

var INT_VAR_DEFAULT

The default behavior is CHOOSE_FIRST_UNBOUND.

INT_VAR_SIMPLE

var INT_VAR_SIMPLE

The simple selection is CHOOSE_FIRST_UNBOUND.

LE

var LE

Move is accepted when the current objective value <= objective.Max.

MAKEACTIVE

var MAKEACTIVE

Operator which inserts an inactive node into a path. Possible neighbors for the path 1 -> 2 -> 3 -> 4 with 5 inactive (where 1 and 4 are first and last nodes of the path) are: 1 -> [5] -> 2 -> 3 -> 4 1 -> 2 -> [5] -> 3 -> 4 1 -> 2 -> 3 -> [5] -> 4

MAKECHAININACTIVE

var MAKECHAININACTIVE

Operator which makes a "chain" of path nodes inactive. Possible neighbors for the path 1 -> 2 -> 3 -> 4 (where 1 and 4 are first and last nodes of the path) are: 1 -> 3 -> 4 with 2 inactive 1 -> 2 -> 4 with 3 inactive 1 -> 4 with 2 and 3 inactive

MAKEINACTIVE

var MAKEINACTIVE

Operator which makes path nodes inactive. Possible neighbors for the path 1 -> 2 -> 3 -> 4 (where 1 and 4 are first and last nodes of the path) are: 1 -> 3 -> 4 with 2 inactive 1 -> 2 -> 4 with 3 inactive

NORMAL_PRIORITY

var NORMAL_PRIORITY

NORMAL_PRIORITY is the highest priority: Demons will be processed first.

OROPT

var OROPT

Relocate: OROPT and RELOCATE. Operator which moves a sub-chain of a path to another position; the specified chain length is the fixed length of the chains being moved. When this length is 1, the operator simply moves a node to another position. Possible neighbors for the path 1 -> 2 -> 3 -> 4 -> 5, for a chain length of 2 (where (1, 5) are first and last nodes of the path and can therefore not be moved): 1 -> 4 -> [2 -> 3] -> 5 1 -> [3 -> 4] -> 2 -> 5 Using Relocate with chain lengths of 1, 2 and 3 together is equivalent to the OrOpt operator on a path. The OrOpt operator is a limited version of 3Opt (breaks 3 arcs on a path).

PATHLNS

var PATHLNS

Operator which relaxes two sub-chains of three consecutive arcs each. Each sub-chain is defined by a start node and the next three arcs. Those six arcs are relaxed to build a new neighbor. PATHLNS explores all possible pairs of starting nodes and so defines n^2 neighbors, n being the number of nodes. Note that the two sub-chains can be part of the same path; they even may overlap.

RELOCATE

var RELOCATE

Relocate neighborhood with length of 1 (see OROPT comment).

SEQUENCE_DEFAULT

var SEQUENCE_DEFAULT

SEQUENCE_SIMPLE

var SEQUENCE_SIMPLE

SIMPLELNS

var SIMPLELNS

Operator which defines one neighbor per variable. Each neighbor relaxes one variable. When a new solution is found the neighborhood is rebuilt from scratch. Consider for instance variables x and y. First x is relaxed and the solver is looking for the best possible solution (with only x relaxed). Then y is relaxed, and the solver is looking for a new solution. If a new solution is found, then the next variable to be relaxed is x.

SPLIT_LOWER_HALF

var SPLIT_LOWER_HALF

Split the domain in two around the center, and choose the lower part first.

SPLIT_UPPER_HALF

var SPLIT_UPPER_HALF

Split the domain in two around the center, and choose the lower part first.

SWAPACTIVE

var SWAPACTIVE

Operator which replaces an active node by an inactive one. Possible neighbors for the path 1 -> 2 -> 3 -> 4 with 5 inactive (where 1 and 4 are first and last nodes of the path) are: 1 -> [5] -> 3 -> 4 with 2 inactive 1 -> 2 -> [5] -> 4 with 3 inactive

TWOOPT

var TWOOPT

Operator which reverses a sub-chain of a path. It is called TwoOpt because it breaks two arcs on the path; resulting paths are called two-optimal. Possible neighbors for the path 1 -> 2 -> 3 -> 4 -> 5 (where (1, 5) are first and last nodes of the path and can therefore not be moved): 1 -> [3 -> 2] -> 4 -> 5 1 -> [4 -> 3 -> 2] -> 5 1 -> 2 -> [4 -> 3] -> 5

UNACTIVELNS

var UNACTIVELNS

Operator which relaxes all inactive nodes and one sub-chain of six consecutive arcs. That way the path can be improved by inserting inactive nodes or swapping arcs.

VAR_PRIORITY

var VAR_PRIORITY

VAR_PRIORITY is between DELAYED_PRIORITY and NORMAL_PRIORITY.

AddConstraint

def AddConstraint(self, c: Constraint) -> 'void'

Adds the constraint 'c' to the model. After calling this method, and until there is a backtrack that undoes the addition, any assignment of variables to values must satisfy the given constraint in order to be considered feasible. There are two fairly different use cases: - the most common use case is modeling: the given constraint is really part of the problem that the user is trying to solve. In this use case, AddConstraint is called outside of search (i.e., with state() == OUTSIDE_SEARCH). Most users should only use AddConstraint in this way. In this case, the constraint will belong to the model forever: it cannot not be removed by backtracking. - a rarer use case is that 'c' is not a real constraint of the model. It may be a constraint generated by a branching decision (a constraint whose goal is to restrict the search space), a symmetry breaking constraint (a constraint that does restrict the search space, but in a way that cannot have an impact on the quality of the solutions in the subtree), or an inferred constraint that, while having no semantic value to the model (it does not restrict the set of solutions), is worth having because we believe it may strengthen the propagation. In these cases, it happens that the constraint is added during the search (i.e., with state() == IN_SEARCH or state() == IN_ROOT_NODE). When a constraint is added during a search, it applies only to the subtree of the search tree rooted at the current node, and will be automatically removed by backtracking. This method does not take ownership of the constraint. If the constraint has been created by any factory method (Solver::MakeXXX), it will automatically be deleted. However, power users who implement their own constraints should do: solver.AddConstraint(solver.RevAlloc(new MyConstraint(…));

The VisitTypePolicy of a node determines how visiting it impacts the type count on the route. For example, for - three temporally incompatible types T1 T2 and T3 - 2 pairs of nodes a1/r1 and a2/r2 of type T1 and T2 respectively, with - a1 and a2 of VisitTypePolicy TYPE_ADDED_TO_VEHICLE - r1 and r2 of policy ADDED_TYPE_REMOVED_FROM_VEHICLE - 3 nodes A, UV and AR of type T3, respectively with type policies TYPE_ADDED_TO_VEHICLE, TYPE_ON_VEHICLE_UP_TO_VISIT and TYPE_SIMULTANEOUSLY_ADDED_AND_REMOVED the configurations UV –> a1 –> r1 –> a2 –> r2, a1 –> r1 –> a2 –> r2 –> A and a1 –> r1 –> AR –> a2 –> r2 are acceptable, whereas the configurations a1 –> a2 –> r1 –> …, or A –> a1 –> r1 –> …, or a1 –> r1 –> UV –> … are not feasible. It also verifies same-vehicle and temporal type requirements. A node of type T_d with a same-vehicle requirement for type T_r needs to be served by the same vehicle as a node of type T_r. Temporal requirements, on the other hand, can take effect either when the dependent type is being added to the route or when it's removed from it, which is determined by the dependent node's VisitTypePolicy. In the above example: - If T3 is required on the same vehicle as T1, A, AR or UV must be on the same vehicle as a1. - If T2 is required when adding T1, a2 must be visited before a1, and if r2 is also visited on the route, it must be after a1, i.e. T2 must be on the vehicle when a1 is visited: … –> a2 –> … –> a1 –> … –> r2 –> … - If T3 is required when removing T1, T3 needs to be on the vehicle when r1 is visited: … –> A –> … –> r1 –> … OR … –> r1 –> … –> UV –> …
