Premium Solver ProFinding Global Solutions with Multistart MethodsIn Premium Solver Pro, the GRG nonlinear Solver is augmented with "multistart" or "clustering" methods for global optimization.
Faster Solution of Nonlinear ProblemsNonlinear problems often have some decision variables which occur linearly in the objective and constraints, while other variables occur nonlinearly (making the problem nonlinear overall). The Premium Solver includes a new option for the GRG nonlinear solver, "Recognize Linear Variables," which allows the Solver to save time at each step when it computes partial derivatives of the problem functions. This option can make solution of nonlinear problems up to 50% faster, depending on the number of variables occurring linearly in the problem. |
