Is it possible to log the trajectory of the simplex? I.e. at every step of the execution, save which variables are basic/non-basic, how the pivot rule was used, etc.

  Hi Grigoris,

  It is currently not possible to access the information you mention at each iteration step of the simplex algorithm. You can access the basic/non-basic information after the optimization has been finished. The simplex pricing rule can set via the SimplexPricing parameter.

  Best regards,
  Jaromił
