• LINDO linear programming solver
• LINGO modeling language for optimization
• Adobe Acrobat Reader
• APL+Win3.5 workspaces

• Student versions of LINDO & LINGO can be downloaded from the web site of LINDO Systems-- these can solve LP problems with up to 150 constraints and 300 variables, including up to 30 integer variables. LINDO is also available on the engineering college's UNIX workstations. Click here for a short tutorial on its use.
• APL is an interactive interpreted computer language including very concise and powerful mathematical functions, oriented toward processing of arrays. An APL workspace is a file containing both APL code and variables.
• Various APL workspaces are available for use on Windows computers. These workspaces perform functions such as evaluating probability distribution functions, analyzing discrete-time and continuous-time Markov chains, queueing models, etc. (In order to use an APL workspace, you must have downloaded also the APL runtime interpreter from the same page.)
• Most of the documents are available from this web site in PDF format, which requires Adobe's Acrobat Reader. This is loaded on the computers in the Engineering College labs, or can be downloaded from Adobe's web site.
