XSLPopt

Purpose

Maximize or minimize an SLP problem

Synopsis

int XPRS_CC XSLPopt(XSLPprob Prob, char *Flags);

Arguments

Prob	The current SLP problem.
Flags	These have the same meaning as for XPRSmaxim and XPRSminim.

Related Controls

Double

XSLP_OBJSENSE  
                     

Determines the direction of optimization: +1 is for minimization, -1 is for maximization.

Integer

XSLP_ALGORITHM	Bit map determining the SLP algorithm(s) used in the optimization.
XSLP_AUGMENTATION	Bit map determining the type of augmentation used to create the linearization.
XSLP_CASCADE	Bit map determining the type of cascading (recalculation of SLP variable values) used during the SLP optimization.
XSLP_LOG	Determines the amount of iteration logging information produced.
XSLP_PRESOLVE	Bit map determining the type of nonlinear presolve used before the SLP optimization starts.

Example

The following example reads an SLP problem from file and then maximizes it using the primal simplex optimizer.

XSLPreadprob("Matrix","");
XSLPsetdblcontrol(Prob, XSLP_OBJSENSE, -1);
XSLPopt(Prob,"p");

Further information

XSLPopt is equivalent to XSLPmaxim (if XSLP_OBJSENSE = -1) or XSLPminim (if XSLP_OBJSENSE = +1).

If XSLPconstruct has not already been called, it will be called first, using the augmentation defined by the control variable XSLP_AUGMENTATION. If determining rows are provided, then cascading will be invoked in accordance with the setting of the control variable XSLP_CASCADE.
