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