As everyone is so concerned about stopping Angel getting 'old age' in his fingers, here is my chip-in - it may help.

Artificial-variable Free Solution Algorithms for LP Models by Hossein Arsham, deals with tremendous changes to basic simplex matrix ops, as originated by Saul Gass. Even in some of Gass' latest books there is no real update to the old 2nd world war work. Here is an update worth a module or a 4k? page somewhere. The Jean-Marc Baillard site (link shown above) has some RPN work in samples on these updates, which show 1/3rd faster routines than the older matrix ops. Arsham' work is a revolution in this field, through his 'push/pull' method.

Programmed in mCode & run on a 41CL the routine speed should be blinding? How does this sound for an interesting/insightful/advanced piece of work (no hardware involved).
