Mosek solver for the network flow models

GAMS
1

Hello,

I am trying to solve the special case of the LP - Network flow model by using Simplex Network algorithm proposed by Mosek. In order to call this algorithm I have to add the following option into GAMS:

Set the parameters
MSK_IPAR_OPTIMIZER to MSK_OPTIMIZER_NETWORK_PRIMAL_SIMPLEX ( taken from the manual of Mosek). Without calling this solver, the model will not be solved like network flow model. Maybe anyone knows what is the right way to define this statment in GAMS. I tried different variations, such as:

option MSK_IPAR_OPTIMIZER = MSK_OPTIMIZER_NETWORK_PRIMAL_SIMPLEX

OR

option MSK_IPAR_OPTIMIZER ( MSK_OPTIMIZER_NETWORK_PRIMAL_SIMPLEX)

but without any success.

One more question: maybe someone knows if there exist additional solvers (of course which are possible to implement via GAMS) for solving linear network flow optimization problems?

Thanks in advance

Could you show the log output or maybe provide the GAMS model so I can try it myself.
