The Runtime Complexity (full) of the given CpxTRS could be proven to be BOUNDS(n^1, INF).


The TRS R consists of the following rules:

   plus(0, Y) -> Y
   plus(s(X), Y) -> s(plus(X, Y))
   min(X, 0) -> X
   min(s(X), s(Y)) -> min(X, Y)
   min(min(X, Y), Z) -> min(X, plus(Y, Z))
   quot(0, s(Y)) -> 0
   quot(s(X), s(Y)) -> s(quot(min(X, Y), s(Y)))

S is empty.

(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 (full) of the given CpxTRS could be proven to be BOUNDS(n^1, INF).


The TRS R consists of the following rules:

   plus(0, Y) -> Y
   plus(s(X), Y) -> s(plus(X, Y))
   min(X, 0) -> X
   min(s(X), s(Y)) -> min(X, Y)
   min(min(X, Y), Z) -> min(X, plus(Y, Z))
   quot(0, s(Y)) -> 0
   quot(s(X), s(Y)) -> s(quot(min(X, Y), s(Y)))

S is empty.

(3) DecreasingLoopProof (LOWER BOUND(ID))
The following loop(s) give(s) rise to the lower bound Omega(n^1):

The rewrite sequence

min(s(X), s(Y)) ->^+ min(X, Y)

gives rise to a decreasing loop by considering the right hand sides subterm at position [].

The pumping substitution is [X / s(X), Y / s(Y)].

The result substitution is [ ].
