Input:
   [ c -> c,
     h(a,h(f(b),c)) -> c ]

Make it flat:
   [ h(a,!cl_1) -> c,
     !cl_1 -> !cl_1,
     h(!cl_0,c) -> !cl_1,
     f(b) -> !cl_0,
     c -> c ]
Time: 0.000 [s]

Make it Complete (R^):
   [ h(a,!cl_1) = c,
     h(!cl_0,c) = !cl_1,
     f(b) = !cl_0 ]
Time: 0.000 [s]

CPNF:
   [ a … a,
     b … b,
     !cl_0 … !cl_0 ]
Time: 0.000 [s]

Now checking all the pairs in CW...

Time to check pairs: 0.000 [s]

The TRS has Uniqueness of Normal Forms.
