I am looking for a solver that contains the generalized network simplex algorithm to solve the generalized flow problem.

It seems that CPLEX network optimizer can solve only the min cost flow problem.
I would like to check if CPLEX network optimizer can solve the generalized flow problem.

Pleas note that the generalized flow problem is different to the min cost flow problem, in terms of flow conservation.
In some arcs of the generalized flow problem, the flow amount can be increased or decreased.

Does anybody know this clearly?

Thank you.

I was wondering if you were able to figure out if we can solve generalized flow problems in CPLEX. I am in the exact same sport as you are right now. 

 

Appreciate your reply.

 

Thanks

Unfortunately, as far as I know, CPLEX network optimizer cannot solve a generalized flow problem.

It solves it using normal lp logic.

I couldn't find any available codes to solve it.

Thanks, I didn't find one either.
