This allows us to solve a non-linear optimization problem as a pseudo-linear one and, hence, achieving a very low elapsed time at each optimization. Matlab16, Linux 16. By default, we set up the cluster so that all jobs run on one core only, and Gurobi doesn't 'honor' all of the normal ways. There are three potential solutions with one of the variables being equal to 6 while the others are equal to 5. We recommend to solve a linearized problem by TANK, CAR, or VAN. Each job must be executed by one computer,. Solver’s basic purpose is to find a solution – that is, values for the decision variables in your model – that satisfies all of the constraints and maximizes or minimizes the objective cell value (if there is one). 2015/8/12 page: 4.
