MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { sum(cons(s(n), x), cons(m, y)) -> sum(cons(n, x), cons(s(m), y)) , sum(cons(0(), x), y) -> sum(x, y) , sum(nil(), y) -> y , weight(cons(n, cons(m, x))) -> weight(sum(cons(n, cons(m, x)), cons(0(), x))) , weight(cons(n, nil())) -> n } Obligation: runtime complexity Answer: MAYBE 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) 'bsearch-popstar (timeout of 60 seconds)' failed due to the following reason: The processor is inapplicable, reason: Processor only applicable for innermost runtime complexity analysis 2) 'Polynomial Path Order (PS) (timeout of 60 seconds)' failed due to the following reason: The processor is inapplicable, reason: Processor only applicable for innermost runtime complexity analysis 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 perSymbol-enrichment and initial automaton 'match'' failed due to the following reason: match-boundness of the problem could not be verified. 2) 'Bounds with minimal-enrichment and initial automaton 'match'' failed due to the following reason: match-boundness of the problem could not be verified. 3) 'Innermost Weak Dependency Pairs (timeout of 60 seconds)' failed due to the following reason: We add the following weak dependency pairs: Strict DPs: { sum^#(cons(s(n), x), cons(m, y)) -> c_1(sum^#(cons(n, x), cons(s(m), y))) , sum^#(cons(0(), x), y) -> c_2(sum^#(x, y)) , sum^#(nil(), y) -> c_3(y) , weight^#(cons(n, cons(m, x))) -> c_4(weight^#(sum(cons(n, cons(m, x)), cons(0(), x)))) , weight^#(cons(n, nil())) -> c_5(n) } and mark the set of starting terms.
