CPXNETsolninfo

The routine CPXNETsolninfo is used to access solution information computed by a previous call to CPXNETprimopt. The solution values are maintained in the object as long as no changes are applied to it with one of the CPXNETchg..., CPXNETcopy... or CPXNETadd...functions.

The arguments to CPXNETsolninfo are pointers to locations where data are to be written. The returned values indicate what is known about the primal and dual feasibility of the current solution. If either piece of information represented by an argument to CPXNETsolninfo is not required, a NULL pointer can be passed for that argument.

Example

 status = CPXNETsolninfo (env, lp, &pfeasind, &dfeasind);

A pointer to the CPLEX environment as returned by CPXopenCPLEX.

A pointer to a CPLEX network problem object as returned by CPXNETcreateprob.

A pointer to an integer variables indicating whether the current solution is known to be primal feasible. Note that a false return value does not necessarily mean that the solution is not feasible. It simply means that the relevant algorithm was not able to conclude that it was feasible when it terminated.

A pointer to an integer variables indicating whether the current solution is known to be dual feasible. Note that a false return value does not necessarily mean that the solution is not feasible. It simply means that the relevant algorithm was not able to conclude that it was feasible when it terminated.

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

CPXNETsolninfo

Parameters:

Returns:

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
net	A pointer to a CPLEX network problem object as returned by `CPXNETcreateprob`.
pfeasind_p	A pointer to an integer variables indicating whether the current solution is known to be primal feasible. Note that a false return value does not necessarily mean that the solution is not feasible. It simply means that the relevant algorithm was not able to conclude that it was feasible when it terminated.
dfeasind_p	A pointer to an integer variables indicating whether the current solution is known to be dual feasible. Note that a false return value does not necessarily mean that the solution is not feasible. It simply means that the relevant algorithm was not able to conclude that it was feasible when it terminated.
