CPXNETgetdj

int CPXPUBLIC CPXNETgetdj(CPXCENVptr env, CPXCNETptr net, double * dj, int begin, int end)

Definition file: cplex.h

Include files: cplex.h

The routine CPXNETgetdj is used to access reduced costs for a range of arcs of the network stored in a network problem object.

For this function to succeed, a solution must exist for the problem object. If the solution is not feasible (CPXNETsolninfo returns 0 in argument pfeasind_p), the reduced costs are computed with respect to an objective function that penalizes infeasibilities.

Example

 status = CPXNETgetdj (env, net, dj, 10, 20);

Parameters:

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
net	A pointer to a CPLEX network problem object as returned by `CPXNETcreateprob`.
dj	Array in which to write requested reduced costs. If NULL is passed, no reduced cost values are returned. Otherwise, `dj` must point to an array of size at least (`end-begin+1`).
begin	Index of the first arc for which a reduced cost value is to be obtained.
end	Index of the last arc for which a reduced cost value is to be obtained. Example status = CPXNETgetdj (env, net, dj, 10, 20);

Returns:

The routine returns zero on success and nonzero if an error occurs.
