Global Optimization 4.1 Released
Loehle Enterprises has released Version 4.1 of Global Optimization, which uses Mathematica.
The new release brings to eight the number of functions for global optimization
problem solving. The new function, GlobalSearch, combines the generalized
derivative-based steepest descent method with a path-following algorithm for
constraint satisfaction. This algorithm adds a new level of reliability to
the package. In addition, several performance enhancements
increase speed dramatically. For example, a 100-variable unconstrained quadratic
minimization problem now takes only 4.5 seconds on a 600-megahertz machine. The
functionality of the nonlinear regression function has been improved with the
addition of ChiSquare, L1, and L2 norms as options for fit criteria. For more information, visit www.wolfram.com/products/applications/globalopt.
