Function Documentation

SCIPconsNonlinearGetRhs()

SCIP_Real SCIPconsNonlinearGetRhs	(	SCIP *	scip,
		SCIP_CONS *	cons,
		SCIP_Bool *	success
	)

returns the right-hand side of an arbitrary SCIP constraint that can be represented as a single nonlinear constraint

Note

The success pointer indicates if the individual contraint handler was able to return the involved values

Parameters

scip	SCIP data structure
cons	constraint for which right-hand side is queried
success	pointer to store whether a valid right-hand side was returned

SCIPconsNonlinearGetLhs()

SCIP_Real SCIPconsNonlinearGetLhs	(	SCIP *	scip,
		SCIP_CONS *	cons,
		SCIP_Bool *	success
	)

returns the left-hand side of an arbitrary SCIP constraint that can be represented as a single nonlinear constraint

Note

The success pointer indicates if the individual contraint handler was able to return the involved values

Parameters

scip	SCIP data structure
cons	constraint to get left-hand side for
success	pointer to store whether a valid left-hand side was returned

SCIPconsNonlinearAddLinearCoef()

SCIP_RETCODE SCIPconsNonlinearAddLinearCoef	(	SCIP *	scip,
		SCIP_CONS *	cons,
		SCIP_VAR *	var,
		SCIP_Real	val
	)

adds the given variable to the input constraint.

Parameters

scip	SCIP data structure
cons	constraint for which row is queried
var	variable of the constraint entry
val	the coefficient of the constraint entry
