WORST_CASE(NON_POLY, ?) proof of /export/starexec/sandbox/benchmark/theBenchmark.xml # AProVE Commit ID: 794c25de1cacf0d048858bcd21c9a779e1221865 marcel 20200619 unpublished dirty The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(EXP, INF). (0) CpxTRS (1) RelTrsToDecreasingLoopProblemProof [LOWER BOUND(ID), 0 ms] (2) TRS for Loop Detection (3) DecreasingLoopProof [FINISHED, 0 ms] (4) BOUNDS(EXP, INF) ---------------------------------------- (0) Obligation: The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(EXP, INF). The TRS R consists of the following rules: g(f(x, y)) -> f(f(g(g(x)), g(g(y))), f(g(g(x)), g(g(y)))) S is empty. Rewrite Strategy: INNERMOST ---------------------------------------- (1) RelTrsToDecreasingLoopProblemProof (LOWER BOUND(ID)) Transformed a relative TRS into a decreasing-loop problem. ---------------------------------------- (2) Obligation: Analyzing the following TRS for decreasing loops: The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(EXP, INF). The TRS R consists of the following rules: g(f(x, y)) -> f(f(g(g(x)), g(g(y))), f(g(g(x)), g(g(y)))) S is empty. Rewrite Strategy: INNERMOST ---------------------------------------- (3) DecreasingLoopProof (FINISHED) The following loop(s) give(s) rise to the lower bound EXP: The rewrite sequence g(f(x, y)) ->^+ f(f(g(g(x)), g(g(y))), f(g(g(x)), g(g(y)))) gives rise to a decreasing loop by considering the right hand sides subterm at position [0,0,0]. The pumping substitution is [x / f(x, y)]. The result substitution is [ ]. The rewrite sequence g(f(x, y)) ->^+ f(f(g(g(x)), g(g(y))), f(g(g(x)), g(g(y)))) gives rise to a decreasing loop by considering the right hand sides subterm at position [1,0,0]. The pumping substitution is [x / f(x, y)]. The result substitution is [ ]. ---------------------------------------- (4) BOUNDS(EXP, INF) popout
