◆ Accept()
|
pure virtualinherited |
Accepts a "delta" given the assignment with which the filter has been synchronized; the delta holds the variables which have been modified and their new value.
If the filter represents a part of the global objective, its contribution must be between objective_min and objective_max. Sample: supposing one wants to maintain a[0,1] + b[0,1] <= 1, for the assignment (a,1), (b,0), the delta (b,1) will be rejected but the delta (a,0) will be accepted. TODO(user): Remove arguments when there are no more need for those.
Implemented in CPFeasibilityFilter, BasePathFilter, and LocalSearchFilterManager.
◆ AddVars()
| void AddVars | ( | const std::vector< IntVar * > & | vars | ) |
Add variables to "track" to the filter.
