@hackage cmu1.4

This package contains a library for unification in commutative monoid and a program that exercises the library.

$ cmu Commutative monoid unification -- :? for help cmu> 2x+y=3z Problem: 2x + y = 3z Unifier: [x : g0 + 3g2,y : g0 + 3g1,z : g0 + g1 + 2g2]

cmu> 2x=x+y Problem: 2x = x + y Unifier: [x : g0,y : g0]

cmu> 64x=41y+a Problem: 64x = a + 41y Unifier: [a : 5g0 + 2g1 + 23g2 + g3 + 64g4,x : 2g0 + 9g1 + g2 + 25g3 + g4 + 41g5,y : 3g0 + 14g1 + g2 + 39g3 + 64g5]
