Statistics and Computation

1.  R Project

Replaces: SAS, SPSS

R is a free and open source statistical computing environment that holds its own against some of the most established proprietary statistical environments.  R is available on all operating systems and is free for download.  R also has a community driven library of add-on packages that are also freely available and cover almost any statistical, mathematical, or optimization need.

Also a great reference manual for those switching from SAS to R is SAS and R: Data Management, Statistical Analysis, and Graphics


2.  RapidMiner

Replaces:  KnowledgeSEEKER

RapidMiner is a data mining software with a graphical front-end.  RapidMiner is suitable for most data mining and data transformation needs.


Mathematical Programming and Optimization

3.  GLPK

Replaces:  AMPL

GLPK is a GNU/free software linear programming software kit.  GLPK is intended for large-scale linear programming, mixed integer programming.  GLPK is based on GNU MathProg (or GMPL) which is considered a subset of the AMPL syntax.  GLPK also has its own solver.

4.  Symphony

Replaces: CPLEX, Gurobi

Symphony is a mixed integer linear programming solver developed under COIN-OR.  Symphony is a flexible framework that offers many methods to customize solver capabilities given problem sets.


5.  OpenSolver

Replaces:  Excel Solver

OpenSolver is a linear an integer optimizer alternative to the Excel Solver in Microsoft Excel.  OpenSolver is based on the COIN-OR CBC engine.  Unlike the Excel Solver there is no software limits to the size of the problem that can be solved.
