Algebraic Modeling Languages (AML) are high-level computer programming languages for describing and solving high complexity problems for large scale mathematical computation (i.e. large scale optimization type problems). One particular advantage of some algebraic modeling languages like AIMMS,〔 AMPL,〔 〕 GAMS〔 or Xpress-Mosel〔 is the similarity of their syntax to the mathematical notation of optimization problems. This allows for a very concise and readable definition of problems in the domain of optimization, which is supported by certain language elements like sets, indices, algebraic expressions, powerful sparse index and data handling variables, constraints with arbitrary names. The algebraic formulation of a model does not contain any hints how to process it. An AML does not solve those problems directly; instead, it calls appropriate external algorithms to obtain a solution. These algorithms are called solvers and can handle certain kind of mathematical problems like: * linear problems * integer problems * (mixed integer) quadratic problems * mixed complementarity problems * mathematical programs with equilibrium constraints * constrained nonlinear systems * general nonlinear problems * non-linear programs with discontinuous derivatives * nonlinear integer problems * global optimization problems * stochastic optimization problems == Core Elements == The core elements of an AML are: * a modeling language interpreter (the AML itself) * solver links * user interfaces (UI) * data exchange facilities 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「algebraic modeling language」の詳細全文を読む スポンサード リンク
