ILOG CPLEX .NET Reference Manual

Cplex.NetworkCallback.IsFeasible Method 

Returns a Boolean value indicating whether the current solution is primal feasible at the moment the callback is called.

protected virtual bool IsFeasible();

Return Value

A Boolean value indicating whether the current solution is primal feasible.

Remarks

Since the network optimizer sees only the embedded network part of the full model, a solution considered to be feasible for the network optimizer may not be so for the full model.
