    • Categories Constrained Nonlinear Optimization, Global Optimization, Optimization Software and Modeling Systems

    Mathematica is an advanced software system that enables symbolic computing, numerics, program code development, model visualization and professional documentation in a unified framework. Our MathOptimizer software package serves to solve global and local optimization models developed using Mathematica. We introduce MathOptimizer’s key features and discuss its usage options that support a range of operational modes. … Read more

    Nonlinear Optimization with GAMS /LGO

  • János Pintér
    • Categories Global Optimization, Optimization Software and Modeling Systems

    The Lipschitz Global Optimizer (LGO) software integrates global and local scope search methods, to handle nonlinear optimization models. Here we discuss the LGO implementation linked to the General Algebraic Modeling System (GAMS). First we review the key features and basic usage of the GAMS /LGO solver option, then present reproducible numerical results to illustrate its … Read more

    We present a review of several professional software products that serve to analyze and solve nonlinear (global and local) optimization problems across a variety of hardware and software environments. The product versions discussed have been implemented for compiler platforms, spreadsheets, algebraic (optimization) modeling languages, and for integrated scientific-technical computing systems. The discussion highlights some of … Read more

    Global and Convex Optimization in Modeling Environments: Compiler-Based, Excel, and Mathematica Implementations

  • János Pintér
    • Categories Applications - Science and Engineering, Global Optimization, Optimization Software and Modeling Systems

    We present a review of several software products that serve to analyze and solve nonlinear (specifically including global) optimization problems across different hardware and software platforms. The implementations discussed are LGO, as a stand-alone, but compiler-dependent modeling and solver environment; its Excel platform implementation; and MathOptimizer, a native solver package for Mathematica users. The discussion … Read more

    Global Optimization: Software, Test Problems, and Applications

  • János Pintér
