Detailed Description

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.

◆ Accept()

bool Accept	(	LocalSearchMonitor *const	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.
