Hello Ashish,
if there are any Lisp sources available, I also would like to know. I 
tried to code something in lisp, but as a novice to linear 
programming I did not very good. We found out that the solver 
included in Microsoft-Excel is faster by a factor 50. 
What I could offer is a simple standard, two-phase simplex. That 
was before I understood the elegance of a dual simplex algorithm, 
which might be faster.
There are some C libraries from Robert J. Vanderbei at 
http://www.princeton.edu/~rvdb/LPbook/
Maybe somebody has the time and skill to write a foreign function 
interface for it.

mailing list so please CC the reply to me at <unity.ncsu.edu. at asureka> Thanks in advance.
