(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 -> f(b),
     h(b,f(c)) -> c,
     b -> f(b),
     b -> f(c),
     h(c,c) -> c ]
TRS:
   [ a -> f(b),
     h(b,f(c)) -> c,
     b -> f(b),
     b -> f(c),
     h(c,c) -> c ]
New rules by rule reversing:
   [ a -> a,
     f(b) -> a,
     h(b,f(c)) -> c,
     f(b) -> b,
     b -> f(c),
     h(c,c) -> c ]
Check distinct normal forms in critical pair closure
convertible distinct normal forms: f(f(c)) = f(c)
