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

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