How do I change a batch of control parameters?
Hi, I am new to Xpress. Is it possible to change control parameters by reading in a parameters file ? I need to be able to quickly change about 60 parameters multiple times.
With the C API you could also use this routine:
int XPRS_CC XPRSsetparam(XPRSprob prob,const char* _paramname, const char* _svalue);
that allows you to set Optimizer controls by string, meaning that you do not have to first check whether the control is an integer or double, such as in:
XPRSsetparam(myprob, "XPRS_PRESOLVE", "1");
