C++ Reference: class SharedSolutionRepository

This documentation is automatically generated.

Method
Add

Return type: void

Arguments: const Solution& solution

Add a new solution. Note that it will not be added to the pool of solution right away. One must call Synchronize for this to happen. Works in O(num_solutions_to_keep_).

GetRandomBiasedSolution

Return type: Solution

Arguments: absl::BitGenRef random

Returns a random solution biased towards good solutions.

GetSolution

Return type: Solution

Arguments: int index

Returns the solution #i where i must be smaller than NumSolutions().

GetVariableValueInSolution

Return type: ValueType

Arguments: int var_index, int solution_index

Returns the variable value of variable 'var_index' from solution 'solution_index' where solution_index must be smaller than NumSolutions() and 'var_index' must be smaller than number of variables.

NumSolutions

Return type: int

Returns the number of current solution in the pool. This will never decrease.

SharedSolutionRepository

Return type: explicit

Arguments: int num_solutions_to_keep

Synchronize

Return type: void

Updates the current pool of solution with the one recently added. Note that we use a stable ordering of solutions, so the final pool will be independent on the order of the calls to AddSolution() provided that the set of added solutions is the same. Works in O(num_solutions_to_keep_).
