Amir and Michael Posted three programs
- recursive.cpp
- appoint.cpp
- simplex_exp.cpp
we will focus on appoint and simplex_exp for our project of developing a fast approach for calculating simplex algorithims
Application of Parallel computing in Simplex method
- The first step is to find and use a reliable source code for simplex algorthim, in order to use it for linear programming problems. SoPlex is one the famous and reliable Open source LP Solvers in C++ Language. http://soplex.zib.de/
(Since SoPlex source code is so complicated to modify in order to use it as a DEA solver, we decided to you the opensource from http://code.google.com/p/cpplex/source/browse/trunk/simplex/#simplex%253Fstate%253Dclosed) - Next step is to learn how to work with Soplex. The following link shows an example of using SoPlex: http://disopt.epfl.ch/files/content/sites/disopt/files/shared/OptInFinance09/zimplfaq.pdf
