XSLPreminim

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 NonLinear 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.
