Can anyone recommend software for conducting linear programming analysis on a 286-based machine? What I'd really like is an add-in for Lotus 123, but a stand-alone would work too. Note that linear programming is not a way of writing source code, but a multivariate statistical technique. Also any suggestions for other newsgroups for this posting would be appreciated.

I don't know who produces it, but I THINK they are related to the people who produce LINDO (a standard stand-alone linear programming package for the PC / many other machines).

I don't know about the recommending bit, but if you have the (anonymous) ftp capability you can get /pc/ts/tslin29.arc from our site. This file contains a linear programming and a linear goal programming program. >Note that linear programming is not a way of writing source code, >but a multivariate statistical technique. Sorry, but you have confused things in here. Linear programming is NOT a multivariate statistical technique (even if it can be applied as a tool in least absolute deviations method in multiple regression analysis.) Linear programming is a method for maximizing (or minimizing) a linear function under linear constraints. The traditional LP task in vector notation is max z = c'x subject to Ax < b - x > 0 - If you are looking for a newsgroup for LP questions, I think that your best bet is sci.math.num-analysis. ...................................................................

It uses a spreadsheet style interface, with some prompting for non-calculation type parameters. It does linear programming and a lot more (transportation problems, PERT/CPM, etc). I don't know if this was developed in house or if it's a commercial product, I used it last semester, and while the user interface is less than intuitive, its' performance on a 5Mhz PC was acceptable.
