The TRS R consists of the following rules: dbl(S(0), S(0)) -> S(S(S(S(0)))) save(S(x)) -> dbl(0, save(x)) save(0) -> 0 dbl(0, y) -> y S is empty. Rewrite Strategy: INNERMOST ---------------------------------------- (1) RelTrsToTrsProof (UPPER BOUND(ID)) transformed relative TRS to TRS ---------------------------------------- (2) Obligation: The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(1, n^1). The TRS R consists of the following rules: dbl(S(0), S(0)) -> S(S(S(S(0)))) save(S(x)) -> dbl(0, save(x)) save(0) -> 0 dbl(0, y) -> y S is empty. Rewrite Strategy: INNERMOST ---------------------------------------- (3) CpxTrsMatchBoundsTAProof (FINISHED) A linear upper bound on the runtime complexity of the TRS R could be shown with a Match-Bound[TAB_LEFTLINEAR,TAB_NONLEFTLINEAR] (for contructor-based start-terms) of 1. The compatible tree automaton used to show the Match-Boundedness (for constructor-based start-terms) is represented by: final states : [1, 2] transitions: S0(0) -> 0 00() -> 0 dbl0(0, 0) -> 1 save0(0) -> 2 01() -> 5 S1(5) -> 4 S1(4) -> 3 S1(3) -> 3 S1(3) -> 1 01() -> 6 save1(0) -> 7 dbl1(6, 7) -> 2 01() -> 2 dbl1(6, 7) -> 7 01() -> 7 0 -> 1 7 -> 2 ---------------------------------------- (4) BOUNDS(1, n^1) ---------------------------------------- (5) RelTrsToDecreasingLoopProblemProof (LOWER BOUND(ID)) Transformed a relative TRS into a decreasing-loop problem. ---------------------------------------- (6) Obligation: Analyzing the following TRS for decreasing loops: The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(n^1, n^1). popout
