(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(b) -> b,
     b -> h(h(c,f(b)),a) ]
TRS:
   [ f(b) -> b,
     b -> h(h(c,f(b)),a) ]
New rules by rule reversing:
   [ f(b) -> b,
     b -> b,
     h(h(c,f(b)),a) -> b ]
confluent TRS:
   [ f(b) -> b,
     b -> b,
     h(h(c,f(b)),a) -> b,
     h(h(c,b),a) -> b ]
