(ignored inputs)COMMENT Cops #647 - #721: generated ground TRSs; evenly distributed in the UNR/UNC/NFP/CR hierarchy submitted by: Bertram Felgenhauer
input TRS:
   [ a -> a,
     a -> h(a,b),
     b -> h(b,f(f(b))),
     b -> b,
     h(b,h(f(a),a)) -> a ]
TRS:
   [ a -> a,
     a -> h(a,b),
     b -> h(b,f(f(b))),
     b -> b,
     h(b,h(f(a),a)) -> a ]
New rules by rule reversing:

     b -> b,
     h(b,f(f(b))) -> b,
     b -> b,

confluent TRS:
   [ a -> a,
     a -> a,
     h(a,b) -> a,
     b -> b,
     h(b,f(f(b))) -> b,
