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