The TRS R consists of the following rules: purge(nil) -> nil purge(.(x, y)) -> .(x, purge(remove(x, y))) remove(x, nil) -> nil remove(x, .(y, z)) -> if(=(x, y), remove(x, z), .(y, remove(x, z))) 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: purge(nil) -> nil purge(.(x, y)) -> .(x, purge(remove(x, y))) remove(x, nil) -> nil remove(x, .(y, z)) -> if(=(x, y), remove(x, z), .(y, remove(x, z))) S is empty. Rewrite Strategy: INNERMOST ---------------------------------------- (3) DecreasingLoopProof (FINISHED) The following loop(s) give(s) rise to the lower bound EXP: The rewrite sequence remove(x, .(y, z)) ->^+ if(=(x, y), remove(x, z), .(y, remove(x, z))) gives rise to a decreasing loop by considering the right hand sides subterm at position [1]. The pumping substitution is [z / .(y, z)]. The result substitution is [ ]. The rewrite sequence remove(x, .(y, z)) ->^+ if(=(x, y), remove(x, z), .(y, remove(x, z))) gives rise to a decreasing loop by considering the right hand sides subterm at position [2,1]. The pumping substitution is [z / .(y, z)]. The result substitution is [ ]. ---------------------------------------- (4) BOUNDS(EXP, INF) popout
