Functions
SCIP_RETCODE	SCIPincludeExprhdlrSum (SCIP *scip)
Sum expression
This expression handler provides the sum function, that is, \[ x \mapsto c + \sum_{i=1}^n a_i x_i \] for some constant c and constant coefficients \(a_i\).
SCIP_RETCODE	SCIPcreateExprSum (SCIP *scip, SCIP_EXPR **expr, int nchildren, SCIP_EXPR **children, SCIP_Real *coefficients, SCIP_Real constant, SCIP_DECL_EXPR_OWNERCREATE((*ownercreate)), void *ownercreatedata)
void	SCIPsetConstantExprSum (SCIP_EXPR *expr, SCIP_Real constant)
SCIP_RETCODE	SCIPappendExprSumExpr (SCIP *scip, SCIP_EXPR *expr, SCIP_EXPR *child, SCIP_Real childcoef)
void	SCIPmultiplyByConstantExprSum (SCIP_EXPR *expr, SCIP_Real constant)
