Nonlinear optimization with GAMS /LGO

نویسنده

  • János D. Pintér
چکیده

The Lipschitz Global Optimizer (LGO) software integrates global and local scope search methods, to handle nonlinear optimization models. This paper introduces 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 performance.

GAMS/LGO Nonlinear Solver Suite: Key Features, Usage, and Numerical Performance

The LGO solver system integrates a suite of efficient global and local scope optimization strategies. LGO can handle complex nonlinear models under ‘minimal’ (continuity) assumptions. The LGO implementation linked to the GAMS modeling environment has several new features, and improved overall functionality. In this article we review the solver options and the usage of GAMS/LGO. We also present ...

Coupled hydrological-economic modelling for optimised irrigated cultivation in a semi-arid catchment of West Africa

Abstract A coupled model system, consisting of a distributed hydrological model and an economic optimization model, is applied 1) to investigate regional interdependencies between irrigated agriculture and regional water balance and 2) to identify optimized cultivation strategies. The coupled model system is applied to a case study for the semi-arid Atankwidi catchment in West Africa. The hydro...
