The routine CPXgetindconstrinfeas
computes
the infeasibility of a given solution for a range of indicator
constraints. The beginning and end of the range must be
specified. For each constraint, the infeasibility value returned is
0 (zero) if the constraint is satisfied. In particular, the infeasibility
value returned is 0 (zero) if the indicator constraint is not active in
the queried solution. Otherwise, the infeasibility value returned
is the amount by which the righthand side of the linear portion of
the constraint must be changed to make the queried solution
valid. It is positive for a less-than-or-equal-to constraint, negative for a
greater-than-or-equal-to constraint, and can be of any sign for an equality
constraint.
Example
status = CPXgetindconstrinfeas (env, lp, NULL, infeasout, 0, CPXgetnumindconstrs(env,lp)-1);
env | A pointer to the CPLEX environment as returned by |
lp | A pointer to a CPLEX problem object as returned by |
x | The solution whose infeasibility is to be computed. May be NULL in which case the resident solution is used. |
infeasout | An array to receive the infeasibility value for each of the indicator constraints. This array must be of length at least ( |
begin | An integer indicating the beginning of the range of indicator constraints whose infeasibility is to be returned. |
