The compatible tree automaton used to show the Match-Boundedness (for constructor-based start-terms) is represented by: final states : [1, 2, 3] transitions: tt0() -> 0 00() -> 0 s0(0) -> 0 and0(0, 0) -> 1 plus0(0, 0) -> 2 activate0(0) -> 3 activate1(0) -> 1 plus1(0, 0) -> 4 s1(4) -> 2 s1(4) -> 4 0 -> 2 0 -> 3 0 -> 4 0 -> 1 ---------------------------------------- (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 (full) of the given CpxTRS could be proven to be BOUNDS(n^1, n^1).
