Google OR-Tools: operations_research::LocalSearchFilterManager Class Reference

Filter manager: when a move is made, filters are executed to decide whether the solution is feasible and compute parts of the new cost. This class schedules filter execution and composes costs as a sum.

◆ FilterEventType

operations_research::LocalSearchFilterManager::LocalSearchFilterManager ( std::vector< FilterEvent > filter_events)
explicit

◆ LocalSearchFilterManager() [2/2]

operations_research::LocalSearchFilterManager::LocalSearchFilterManager ( std::vector< LocalSearchFilter * > filters)
explicit

◆ Accept()

bool operations_research::LocalSearchFilterManager::Accept ( LocalSearchMonitor * monitor,
const Assignment * delta,
const Assignment * deltadelta,
int64_t objective_min,
int64_t objective_max )

Returns true iff all filters return true, and the sum of their accepted objectives is between objective_min and objective_max. The monitor has its Begin/EndFiltering events triggered.
