Pyomo
Pyomo, short for Python Optimization Modeling Objects, was created in 2008 by William E. Hart and the COIN-OR project team. Pyomo is a Python-based, open-source modeling language for formulating and solving optimization problems, including linear, nonlinear, and mixed-integer programming. It is widely used in operations research, energy systems, supply chain planning, and industrial optimization.
AMPL
AMPL, short for A Mathematical Programming Language, was created in 1985 by Robert Fourer, David Gay, and Brian Kernighan. AMPL is a high-level modeling language designed for formulating and solving large-scale mathematical optimization problems, including linear, nonlinear, and mixed-integer programming. It is widely used in operations research, engineering, economics, energy planning, and supply chain management.
GAMS (General Algebraic Modeling System)
GAMS, short for General Algebraic Modeling System, was created in 1976 by Richard E. Rosenthal and colleagues. GAMS is a high-level modeling system designed for building and solving large-scale mathematical optimization problems, including linear, nonlinear, and mixed-integer programming. It is used in operations research, economics, energy planning, supply chain optimization, and engineering systems.
