Loehle Enterprises Releases Global Optimization 4.0
March 20, 2001--Loehle Enterprises announces the release of Global
Optimization 4.0. Global Optimization is a collection of
functions for global nonlinear optimization.
Currently distributed in more than 20
countries worldwide and in use since early 1998, Global Optimization can
be used for nonlinear least-squares model estimation, maximum likelihood
analysis, financial analysis (investment allocation and derivative hedging
with quadratic programming), engineering design, optimal control,
scheduling, vehicle routing, and other applications.
Global Optimization 4.0 introduces several new functions and key
updates that were unavailable in previous releases.
- The new function NLRegression can solve nonlinear and
constrained regression problems.
- The function MultiStartMin now includes equality constraints.
- The new function MaxLikelihood can solve maximum likelihood
estimation problems. Problems can also be constrained to obtain better
- Like the function InterchangeMethodMin, the new function
TabuSearchMin solves 0-1 integer programming problems such as
routing, traveling salesman, minimal spanning tree, and other discrete
network problems even when the objective function is nonlinear.
TabuSearchMin provides increased efficiency when solving
