Usage
Mixed Integer Users OnlyDescription
The routine CPXgetmipcallbackfunc() is used to access the user-written callback routine which will be called prior to solving each subproblem in the branch-and-bound tree during the optimization of a mixed integer program. This routine works in the same manner as the CPXgetlpcallbackfunc() routine. It enables the user to create a separate callback function to be called during the solution of mixed integer programming problems.Return Value
The routine returns a zero on success, and a nonzero if an error occurs.Synopsis
void CPXgetmipcallbackfunc (CPXENVptr env,
int (CPXPUBLIC **callback_p)
(CPXENVptr, void * int, void *),
void **cbhandle_p);
CPXgetmipcallbackfunc() routine are identical to those of the CPXgetlpcallbackfunc(). The prototype for the callback function is identical as well.status = CPXgetmipcallbackfunc (env, mycallback, NULL);
