Hi, I am trying to convert a primal LP problem into it's corresponding dual. I obtained a non-zero solution for the primal model but as for the dual model I obtained a dual optimal solution of zero instead. Does gurobi have anything which helps in the conversion of primal and dual?

Thank you,

Sheng Hui

  Hi Sheng Hui,

  Gurobi currently does not offer a tool to write the dual problem. You could try using a free online tool such as the atozmath tool.

  Best regards,
