MAYBE 'epo* (timeout of 60.0 seconds)' -------------------------------- Answer: MAYBE Input Problem: innermost runtime-complexity with respect to Rules: { from(X) -> cons(X, from(s(X))) , 2ndspos(0(), Z) -> rnil() , 2ndspos(s(N), cons(X, Z)) -> 2ndspos(s(N), cons2(X, Z)) , 2ndspos(s(N), cons2(X, cons(Y, Z))) -> rcons(posrecip(Y), 2ndsneg(N, Z)) , 2ndsneg(0(), Z) -> rnil() , 2ndsneg(s(N), cons(X, Z)) -> 2ndsneg(s(N), cons2(X, Z)) , 2ndsneg(s(N), cons2(X, cons(Y, Z))) -> rcons(negrecip(Y), 2ndspos(N, Z)) , pi(X) -> 2ndspos(X, from(0())) , plus(0(), Y) -> Y , plus(s(X), Y) -> s(plus(X, Y)) , times(0(), Y) -> 0() , times(s(X), Y) -> plus(Y, times(X, Y)) , square(X) -> times(X, X)} Proof Output: The input cannot be shown compatible
