(0) CpxTRS (1) RelTrsToDecreasingLoopProblemProof [LOWER BOUND(ID), 0 ms] (2) TRS for Loop Detection (3) DecreasingLoopProof [LOWER BOUND(ID), 0 ms] (4) BEST (5) proven lower bound (6) LowerBoundPropagationProof [FINISHED, 0 ms] (7) BOUNDS(n^1, INF) (8) TRS for Loop Detection ---------------------------------------- (0) Obligation: The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(n^1, INF). The TRS R consists of the following rules: ack_in(0, n) -> ack_out(s(n)) ack_in(s(m), 0) -> u11(ack_in(m, s(0))) u11(ack_out(n)) -> ack_out(n) ack_in(s(m), s(n)) -> u21(ack_in(s(m), n), m) u21(ack_out(n), m) -> u22(ack_in(m, n)) u22(ack_out(n)) -> ack_out(n) 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(n^1, INF). The TRS R consists of the following rules: ack_in(0, n) -> ack_out(s(n)) ack_in(s(m), 0) -> u11(ack_in(m, s(0))) u11(ack_out(n)) -> ack_out(n) ack_in(s(m), s(n)) -> u21(ack_in(s(m), n), m) u21(ack_out(n), m) -> u22(ack_in(m, n)) u22(ack_out(n)) -> ack_out(n) S is empty. Rewrite Strategy: INNERMOST ---------------------------------------- (3) DecreasingLoopProof (LOWER BOUND(ID)) The following loop(s) give(s) rise to the lower bound Omega(n^1): The rewrite sequence ack_in(s(m), s(n)) ->^+ u21(ack_in(s(m), n), m) gives rise to a decreasing loop by considering the right hand sides subterm at position [0]. The pumping substitution is [n / s(n)]. The result substitution is [ ]. ---------------------------------------- (4) Complex Obligation (BEST) ---------------------------------------- (5) Obligation: Proved the lower bound n^1 for the following obligation: The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(n^1, INF). The TRS R consists of the following rules:
