LinProg.NET ----------- LinProg.NET is a framework for mathematical programming implemented on .NET platform. This framework is supporting linear, integer, boolean and quadratic programming. Framework is written on Microsoft .NET version 2.0. ---------------- Version Changes: ---------------- ver. 0.5.5 ---------- Fixed some errors in modified simplex methods. Alpha version of parallel algorithm for Branch and Bound method that executed on Alchemi .NET Grid. This algorithm turns on with "-grid" command line option. There must be Alchemi.Core.dll in program directory. (You have to recompile project with grid support. For this create directory "lib" and copy Alchemi.Core.dll in this directory. For building project use Nant) Changed class "Provider": Now for parse input task you must load it into provider - method LoadTaskToParcer(string TaskFileName). See LPConsole.cs sources. Changed class "SLPProvider" to "LinProgProvider" Added parser for format *.lp files (lp_solve tasks format) ver. 0.5 -------- Included method based on Branch and Bound method for solving linear-integer programming tasks. ver. 0.4 -------- Add support of modified simplex method. Add support of parametrical analysis. Improved logging. Now log runs in separate thread and do not slow task solving. ------- ver 0.3 ------- Supported simple and dual simplex method MPS, SIM, PRB task format support ----------------------- Command line parameters: ----------------------- LPConsole <-options> <task-file> Options: -grid try to solve task with linear-integer programming method in Alchemi .NET Grid -int try to solve task with linear-integer programming method -con console output -file file output, will be created file with extension ".repout" -max task extremization maximum (only for MPS files) -min task extremization on minimum (only for MPS files) -fib try to find POSITIVE identity basis after task canonization -fab try to find ANY identity basis after task canonization -dls try to solve task with dual simplex method -mds try to solve task with modified simplex method -dnc Do not canonize task Task file: *.sim task in sim format *.prb task in prb format (quite extended sim format) *.mps task in mps format (by default task is solving on maximum) *.lp task in lp format (see lp_solve solving package) By default used modified simplex method. But you may use options to change method (see above) or in particular task set in section [Header] parameter "Method". For this parameter is permitted following values "Dual" and "Modified". For output details try to change next setting.xml keys (accepted values - "true" or "false"): doMission, doTasks, doTable ,doStep, doMatrix, doVectors Thanks to: Rьdiger Klaehn from Lambda Software for generic Set class.
