What’sBest! is an add-in to Excel that allows you to build large scale optimization models in a free form layout within a spreadsheet. What’sBest! combines the proven power of Linear, Nonlinear (convex and nonconvex/Global), Quadratic, Quadratically Constrained, Second Order Cone, Semi-Definite, Stochastic, and Integer optimization with Microsoft Excel — the most popular and flexible business modeling environment in use today. The recently released What’sBest! 16.0 includes a number of significant enhancements and new features. See how to formulate SP Models in What’sBest!.

User Manual (in printed form and available via the online Help) that fully describes the commands and features of the program. Also included in the manual is discussion of the major classes of linear, integer and nonlinear optimization problems along with over two dozen real world based examples that you can modify and expand, … more
|SEVERAL TIMES FASTER ON LINEAR MODELS WITH MANY MORE VARIABLES THAN CONSTRAINTS
The Simplex Solvers have been enhanced to solve linear models with several times more variables than constraints substantially faster.
|ADDED SUPPORT FOR MULTIPLE OBJECTIVE OPTIMIZATION
For linear models, users can provide a prioritized list of objective functions and What’sBest! will perform Lexico/Pre-emptive priority optimization. The solver will optimize on the first objective, constraint it to the optimal value and resolve on the next objective. Then, constraint it and move to the next.
FASTER WHEN SIMULTANEOUSLY SOLVING LINEAR MODELS USING DIFFERENT SOLVERS
An improved feature allows users to concurrently run the Primal Simplex, Dual Simplex, and Barrier solver each on a separate core ensuring the solution in the shortest time regardless of which solver is fastest.
IMPROVED SUPPORT FOR USING NETWORK AND CLOUD DRIVES
The new release offers improved support for storing models on network drives and cloud drives.
|INTEGER SOLVER IMPROVEMENTS
Better performance on many integer models has been achieved through improved selection of default settings for cut generation and solution heuristics.
SUPPORT (FASTER SOLVE TIMES) FOR ADDITIONAL COMPOSITE FUNCTIONS
WBLOGABEXPX ln(a + b * exp(x))
ENHANCEMENTS TO THE QUADRATIC/CONIC SOLVERS
Models with ex and xk terms are solved faster — so called Barrier Solver exponential and power cones.
|IMPROVED INSTALLATION AND USER INTERFACE
The format and layout of some dialog boxes have been improved to provide more information and make them more user-friendly. Several enhancements have been made to improve the installation process.
|NUMEROUS GLOBAL SOLVER ENHANCEMENTS
The ability to recognize and exploit convexity of various composite functions has been substantially improved. Performance has been improved for convex-concave type functions. Models with ratio/fractional objective solve an order of magnitude faster. Performance on on-convex Quadratically Constrained Quadratic Programs and been substantially improved.
