Detailed Description

primal heuristic that tries a given solution

Author

Marc Pfetsch

This heuristic takes a solution from somewhere else via the function SCIPheurPassSolTrySol(). It then tries to commit this solution. It is mainly used by cons_indicator, which tries to correct a given solution, but cannot directly submit this solution, because it is a constraint handler and not a heuristic.

Function Documentation

SCIP_RETCODE SCIPincludeHeurTrySol

(

SCIP *

scip

)

creates the trysol primal heuristic and includes it in SCIP

Parameters

scip	SCIP data structure

SCIP_RETCODE SCIPheurPassSolTrySol	(	SCIP *	scip,
		SCIP_HEUR *	heur,
		SCIP_SOL *	sol
	)

pass solution to trysol heuristic

Parameters

scip	SCIP data structure
heur	trysol heuristic
sol	solution to be passed

SCIP_RETCODE SCIPheurPassSolAddSol	(	SCIP *	scip,
		SCIP_HEUR *	heur,
		SCIP_SOL *	sol
	)

pass solution to trysol heuristic which just gets added (without checking feasibility

Parameters

scip	SCIP data structure
heur	trysol heuristic
sol	solution to be passed
