MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { f(x, 0(), 0()) -> s(x) , f(0(), y, 0()) -> s(y) , f(0(), 0(), z) -> s(z) , f(0(), s(0()), s(0())) -> s(s(0())) , f(0(), s(0()), s(s(z))) -> f(0(), s(0()), z) , f(0(), s(s(y)), s(0())) -> f(0(), y, s(0())) , f(0(), s(s(y)), s(s(z))) -> f(0(), y, f(0(), s(s(y)), s(z))) , f(s(x), 0(), s(z)) -> f(x, s(0()), z) , f(s(x), s(y), 0()) -> f(x, y, s(0())) , f(s(x), s(y), s(z)) -> f(x, y, f(s(x), s(y), z)) , f(s(0()), y, z) -> f(0(), s(y), s(z)) } Obligation: innermost runtime complexity Answer: MAYBE None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'empty' failed due to the following reason: Empty strict component of the problem is NOT empty. 2) 'Best' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'WithProblem (timeout of 60 seconds)' failed due to the following reason: Computation stopped due to timeout after 60.0 seconds. 2) 'Best' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'WithProblem (timeout of 30 seconds) (timeout of 60 seconds)' failed due to the following reason: Computation stopped due to timeout after 30.0 seconds. 2) 'Best' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'Polynomial Path Order (PS) (timeout of 60 seconds)' failed due to the following reason: The input cannot be shown compatible 2) 'bsearch-popstar (timeout of 60 seconds)' failed due to the following reason: The input cannot be shown compatible 3) 'Fastest (timeout of 5 seconds) (timeout of 60 seconds)' failed due to the following reason: None of the processors succeeded. Details of failed attempt(s): ----------------------------- 1) 'Bounds with minimal-enrichment and initial automaton 'match'' failed due to the following reason: match-boundness of the problem could not be verified. 2) 'Bounds with perSymbol-enrichment and initial automaton 'match'' failed due to the following reason: match-boundness of the problem could not be verified.
