◆ checkSolOrig()

SCIP_RETCODE checkSolOrig	(	SCIP *	scip,
		SCIP_SOL *	sol,
		SCIP_Bool *	feasible,
		SCIP_Bool	printreason,
		SCIP_Bool	completely,
		SCIP_Bool	checkbounds,
		SCIP_Bool	checkintegrality,
		SCIP_Bool	checklprows,
		SCIP_Bool	checkmodifiable )

static

checks solution for feasibility in original problem without adding it to the solution store; to improve the performance we use the following order when checking for violations:

variable bounds
constraint handlers with positive or zero priority that don't need constraints (e.g. integral constraint handler)
original constraints
constraint handlers with negative priority that don't need constraints (e.g. Benders' decomposition constraint handler)

Parameters

scip	SCIP data structure
sol	primal CIP solution
feasible	stores whether given solution is feasible
printreason	Should the reason for the violation be printed?
completely	Should all violations be checked if printreason is true?
checkbounds	Should the bounds of the variables be checked?
checkintegrality	Has integrality to be checked?
checklprows	Do constraints represented by rows in the current LP have to be checked?
checkmodifiable	have modifiable constraint to be checked?

static

checks solution (fp or exact) for exact feasibility in original problem without adding it to the solution store; to improve the performance we use the following order when checking for violations:

variable bounds
constraint handlers with positive or zero priority that don't need constraints (e.g. integral constraint handler)
original constraints
constraint handlers with negative priority that don't need constraints (e.g. Benders' decomposition constraint handler)

Parameters

scip	SCIP data structure
sol	primal CIP solution
feasible	stores whether given solution is feasible
printreason	Should the reason for the violation be printed?
