Can anyone help on how to use LinearProgramming for not-so-small
I have a program with about 80 variables and about 120 constraints,
everything real. This just sits for more than a day on every machine
I have tried it on. (I have run Mathematica 2.2.2 on a PowerMac 8000,
and Mathematica 3.0 on a fast mainframe here.)
The next smaller version, with 64 variables and 90 constraints, takes
just a few minutes on the mainframe.
These are pretty small linear programs, so is there some memory limit I
need to raise, or a faster version of the LinearProgramming command?
Thanks in advance for any help,
