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!.

|BETTER PERFORMANCE ON LINEAR MODELS WITH IMPROVED SIMPLEX SOLVERS
Enhancements to the Simplex solvers boost speed on linear models. Models solve an average of 18% faster using primal simplex and 15% faster for dual simplex.
SIGNIFICANTLY FASTER ON LARGE QUADRATIC MODELS
Improvements in handling large quadratic matrices, e.g. 1000 x 1000, provide substantial performance improvement solving Quadratic Programming models.
IMPROVED HANDLING OF MODELS WITH ALL DIFFERENT AND DISCONTINUOUS FUNCTIONS
Models that utilize the ALLDIFF function and discontinuous functions such as MOD(x,k), INT(x), ROUND(x), can be solved more quickly.
FASTER WHEN SIMULTANEOUSLY SOLVING LPs USING DIFFERENT SOLVERS
In situations in which it may be difficult to predict whether the Primal, Dual or Barrier Solver will provide the fastest solution to a linear model, an improved Multi-Core feature allows you to assign each solver to a separate core and run them concurrently. So, you are ensured the solution in the shortest time regardless of which solver is fastest.
|MULTI-START NLP SOLVER NOW SUPPORTS A TARGET VALUE
Users can specify a target value for the objective function. As soon as any multi-start thread achieves a specified target all threads stop.
|NEW ENGINEERING DESIGN FUNCTIONS
Support has been added for new arithmetic functions, WBSIGNPOWER, WBLMTD, WBRLMTD, that can be useful in various engineering design, e.g., nonlinear network and heat exchanger models.
| BUILD PORTFOLIO MODELS EASIER
A new WBQUADPROD functions has been added to greatly simplify the expression of portfolio models.
