LINDO Systems recently announced What'sBest 9.0, a new release of their Solver add-in for Excel that is faster and more powerful and adds support for the recently released Microsoft Office 2007.

What'sBest 9.0 is an average of 80 percent faster at solving linear models due to enhancements to the Dual and Primal Simplex solvers. The Barrier solver is an average of 20 percent faster on large-scale linear and quadratic models. Enhancements to the Simplex and Barrier solvers also improve handling of numerically difficult problems.

The Integer solver is an average of 40 percent faster on a wide range of integer models. It also includes a number of enhancements to more quickly find and improve integer solutions and to better exploit a wider range of problem structures.

The general Nonlinear Solver is an average of 25 percent faster on highly nonlinear and complex models. The Global solver includes a number of enhancements for improving robustness on solving nonconvex nonlinear models to global optimality.

Release 9.0 has expanded support to include the recently released Microsoft Office Excel 2007 in addition to support for Excel XP and Excel 2003. Function support has been greatly expanded with the new release.
