Unlike the Simplex solvers that move along the exterior of the feasible region, the Barrier solver moves through the interior space to find the optimum. The Barrier option utilizes a barrier or interior point method to solve linear models. The optional Barrier solver provides an alternative means of solving linear models. The solver dynamically chooses the best pricing option based upon problem characteristics. Pricing options, for instance, include partial pricing and Devex. The base version includes the Primal and Dual Simplex solvers, which incorporate numerous enhancements for maximum speed and robustness.
What's Best! is available with three state of the art solvers for linear models. What's Best! is able to solve complex and numerically difficult problems that competing products simply cannot. Reliabilityĭay in and day out, thousands of companies around the world rely on What's Best! to provide critical solutions to their toughest optimization problems. What's Best! users routinely solve models of well over 100,000 variables. While competing spreadsheet solvers boast of "industrial strength" versions handling LP models of up to 2,000 variables, the largest version of What's Best! has no capacity limit. Its commercial quality Linear Programming solver combines with superior Integer Programming technology to set a new standard in optimization speed. When it comes to speed, What's Best! outperforms stand alone solvers, much less any competing spreadsheet solver. The internal linear, nonlinear and integer solvers utilize state-of-the-art techniques, and our dedication to ongoing development will ensure their continued superiority. What's Best! offers unmatched solution speed, capacity and reliability.
