inequalities in MAXIMA



For woking with inequalities, Maxima also has code for the simplex algorithm. I don't know a great 
deal about this package; here are two examples:

 (%i7) load(simplex)$
 (%i13) minimize_lp(x,[1 < x, x < y, y < 23]);
 (%o13) [1,[y=23,x=1]]

 (%i14) maximize_lp(x,[1 < x, x < y, y < 23]);
 (%o14) [23,[y=23,x=23]]
