Solver for Excel 2011 for Mac has the same new features and user interface as Solver for Excel 2010 for Windows -- which is greatly enhanced over Solver for Excel 2007.
Includes New Evolutionary Solving Method
Based on genetic algorithms, this method complements Solver's linear programming and nonlinear optimization methods.
Global Optimization for Nonlinear Models
Automatically run the GRG Nonlinear Solver from multiple, intelligently chosen starting points, to find better solutions when the old Solver would be "trapped" in a local optimum.
