C++ Reference: class CoreBasedOptimizer
Note: This documentation is automatically generated.
Same as MinimizeIntegerVariableWithLinearScanAndLazyEncoding() but use
a core-based approach instead. Note that the given objective_var is just used
for reporting the lower-bound/upper-bound and do not need to be linked with
its linear representation.
Unlike MinimizeIntegerVariableWithLinearScanAndLazyEncoding() this function
just return the last solver status. In particular if it is INFEASIBLE but
feasible_solution_observer() was called, it means we are at OPTIMAL.
TODO(user): Change the algo slighlty to allow resuming from the last
aborted position. Currently, the search is "resumable", but it will restart
some of the work already done, so it might just never find anything.
A different way to encode the objective as core are found.
If the vector if literals is passed it will use that, otherwise it will
encode the passed integer variables. In both cases, the vector used should
be of the same size as the coefficients vector.
It seems to be more powerful, but it isn't completely implemented yet.
TODO(user):
- Support resuming for interleaved search.
- Implement all core heurisitics.
