![]() ![]() It also looks forward to possible enhancements to AMPL. This paper gives an overview of AMPL and its interaction with solvers and discusses some problem transformations and implementation techniques. ![]() The freely available AMPL/solver interface library (ASL) facilitates interfacing with solvers. For continuous problems, AMPL makes first and second derivatives available via automatic differentiation. More generally, AMPL permits stating and solving problems with complementarity constraints. AMPL addresses both continuous and discrete optimization problems and offers some constraint programming facilities for the latter. It also lets one modify problem formulations and solve sequences of problems. ![]() The AMPL command language permits computing and displaying information about problem details and solutions returned by solvers. AMPL does some problem transformations and makes relevant problem information available to solvers. AMPL lets one use notation close to familiar mathematical notation to state variables, objectives, and constraints and the sets and parameters that may be involved. A modeling language, such as AMPL, facilitates experimenting with formulations and simplifies using suitable solvers to solve the resulting optimization problems. Sometimes finding a good formulation takes considerable effort. Optimization problems arise in many contexts. ![]()
