Functions
SCIP_RETCODE	SCIPincludeExprhdlrErf (SCIP *scip)
Gaussian error function expression
This expression handler provides the Gaussian error function, that is \[ x \mapsto \frac{2}{\sqrt{\pi}}\int_0^x \exp(-t^2) dt. \] Attention The implementation of this expression handler is incomplete. It is not usable for most use cases so far.
SCIP_RETCODE	SCIPcreateExprErf (SCIP *scip, SCIP_EXPR **expr, SCIP_EXPR *child, SCIP_DECL_EXPR_OWNERCREATE((*ownercreate)), void *ownercreatedata)
SCIP_Bool	SCIPisExprErf (SCIP *scip, SCIP_EXPR *expr)

Function Documentation

SCIPcreateExprErf()

SCIP_RETCODE SCIPcreateExprErf	(	SCIP *	scip,
		SCIP_EXPR **	expr,
		SCIP_EXPR *	child,
		SCIP_DECL_EXPR_OWNERCREATE((*ownercreate))	,
		void *	ownercreatedata
	)

creates an erf expression

Attention

The implementation of erf expressions is incomplete. They are not usable for most use cases so far.

Parameters

scip	SCIP data structure
expr	pointer where to store expression
child	child expression
ownercreatedata	data to pass to ownercreate
