(ignored inputs)COMMENT Cops #647 - #721: generated ground TRSs; evenly distributed in the UNR/UNC/NFP/CR hierarchy submitted by: Bertram Felgenhauer
Input:
   [ a -> c,
     c -> a,
     c -> h(a,c) ]

Make it flat:
   [ a -> c,
     c -> a,
     c -> h(a,c) ]
Time: 0.000 [s]

Make it Complete (R^):
   [ h(a,a) = c,
     a = h(a,c),
     a = h(c,c),
     h(a,a) = a,
     a = h(c,a),
     h(c,a) = c,
     h(a,a) = h(c,c),
     h(a,a) = h(c,a),
     h(c,c) = h(c,a),
     h(a,a) = h(a,c),
     h(c,a) = h(a,c),
     h(c,c) = h(a,c),
     h(c,c) = c,
     a = c,
     c = h(a,c) ]
Time: 0.004 [s]

The number of normal forms that must be checked: 404
Time: 0.037 [s]

Now checking all the pairs...

Time to check pairs: 0.034 [s]

The TRS has Uniqueness of Normal Forms.
Total Time: 0.075 [s]
