发信人: hjdwg (小鱼儿), 信区: MathTools 标题: 推荐两个lindo的替代产品发信站: BBS 水木清华站 (Sun Oct 3 12:07:51 2004), 站内 glpk http://www.gnu.org/software/glpk/glpk.html The GLPK package includes the following main components: Revised simplex method. Primal-dual interior point method. Branch-and-bound method. Translator for GNU MathProg. Application program interface (API). Stand-alone LP/MIP solver. 目前最新的版本是4.7 lp_solver http://groups.yahoo.com/group/lp_solve Mixed Integer Programming (MIP) solver This group contains the latest version of lp_solve, a free (see LGPL in the Files section for the GNU lesser general public license) linear (integer) programming solver with full source, examples and manuals. lp_solve solves pure linear, (mixed) integer/binary, semi-continuous and special ordered sets (SOS) models. lp_solve has no limit on model size and accepts both lp or mps input files. It can also be called as a library from different languages like C, VB, .NET, Delphi, Excel, Java, ... lp_solve is written in ANSI C and can be compiled on many different platforms like Linux and WINDOWS. 目前最新版本是5.1 两者都是免费的软件，可解线性规划、混和整数规划，且无变量个数限制。支持多种建模语言，包括mps格式、lp格式、mathprog格式。其中lp格式与lindo的建模语言非常类似，很容易学。应该说功能上完全超过目前我们能获得的lindo（变量限制），当然求解速度可能会比商业软件低些，但对于普通的问题，压根就看不出来。网上也有人提供matlab的mex接口。这对于解需要解（混和）整数规划的问题来说，是非常好的选择。
