Abstract
Decision problems—arising in various scientific, engineering and economic contexts—are frequently modeled by optimizing the value of suitable objective function under stated feasibility constraints. Global optimization (GO) is aimed at finding the best solution of such decision models, in the possible presence of multiple locally optimal solutions.
This paper discusses a modelling environment for continuous global optimization. The program system LGO serves to analyse and solve nonlinear optimization models under very general—continuity or Lipschitz—structural assumptions. Hence, it is particularly suitable to handle GO problems related to complete stand-alone (‘black box’) system models, and to other models supported only by limited (or difficult to use) analytical information.
LGO integrates several robust and efficient, derivative-free, global and local scope solver modules: these can be applied in automatic or interactive operational modes. The system also has model visualization capabilities. LGO can be directly embedded under a menu-driven user interface, to assist the application development process on personal computers. It is also available for workstation platforms, and can be linked to a variety of advanced numerical modeling and visualization environments.
