XSLPreminim

---

Purpose

Continue the minimization of an SLP problem

Synopsis

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

Arguments

Prob	The current SLP problem.
Flags	These have the same meaning as for XSLPminim.

Example

The following example optimizes the SLP problem for up to 10 SLP iterations. If it has not converged, it saves the file and continues for another 10.

int Status;

XSLPsetintcontrol(Prob, XSLP_ITERLIMIT, 10);
XSLPminim(Prob,"");
XSLPgetintattrib(Prob, XSLP_STATUS, &Status);
if (Status & XSLP_MAXSLPITERATIONS) {
  XSLPsave(Prob);
  XSLPsetintcontrol(Prob, XSLP_ITERLIMIT, 20);
  XSLPreminim(Prob,"");
}

Further information

This allows Xpress-SLP to continue the minimization of a problem after it has been terminated, without re-initializing any of the parameters. In particular, the iteration count will resume at the point where it previously stopped, and not at 1.
