CPXgetmipslack

int CPXPUBLIC CPXgetmipslack(CPXCENVptr env, CPXCLPptr lp, double * slack, int begin, int end)

Definition file: cplex.h

Include files: cplex.h

The routine CPXgetmipslack is used to access a range of slack variables for the current mixed integer solution. The beginning and end of the range must be specified.

The routine returns zero on success and nonzero if an error occurs. If no integer solution has been found, the value CPXERR_NO_INT_SOLUTION is returned.

Example

 status = CPXgetmipslack (env, lp, slack, 0,
                          CPXgetnumrows(env,lp)-1);

See also the example mipex1.c in the standard distribution.

Parameters:

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
lp	A pointer to a CPLEX problem object as returned by `CPXcreateprob`.
slack	An array to contain the values of the primal slack variables for the problem. This array must be of length at least `(end-begin+1)`. If successful, `slack[0]` through `slack[end-begin]` contain the slack variables `begin` through `end`.
begin	An integer indicating the beginning of the range of slack values to be returned.
end	An integer indicating the end of the range of slack values to be returned. Example status = CPXgetmipslack (env, lp, slack, 0, CPXgetnumrows(env,lp)-1); See also the example `mipex1.c` in the standard distribution.
