CPXXchgobjoffset and CPXchgobjoffset
The routine
CPXXchgobjoffset/CPXchgobjoffset
changes the constant offset of the objective function for a problem.
int CPXXchgobjoffset( CPXCENVptr env, CPXLPptr lp, double offset )
int CPXchgobjoffset( CPXCENVptr env, CPXLPptr lp, double offset )
Description
The routine
CPXXchgobjoffset/CPXchgobjoffset
changes the constant offset of the objective function for a problem.
Arguments
- env
-
A pointer to the CPLEX environment as returned by
CPXXopenCPLEX/CPXopenCPLEX. - lp
-
A pointer to a CPLEX problem object as returned by
CPXXcreateprob/CPXcreateprob. - offset
- A double value that specifies the new constant objective offset of the problem.
Return
The routine returns 0 (zero) if successful or an error code otherwise.Example
CPXchgobjoffset (env, lp, 3.14);
