Obligation:
The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(n^1, n^1).


The TRS R consists of the following rules:

   eq0(S(x'), S(x)) -> eq0(x', x)
   eq0(S(x), 0) -> 0
   eq0(0, S(x)) -> 0
   eq0(0, 0) -> S(0)

S is empty.
Rewrite Strategy: INNERMOST

(1) RelTrsToTrsProof (UPPER BOUND(ID))

----------------------------------------

(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:

   eq0(S(x'), S(x)) -> eq0(x', x)
   eq0(S(x), 0) -> 0
   eq0(0, S(x)) -> 0
   eq0(0, 0) -> S(0)

S is empty.

----------------------------------------

(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]
transitions: 
S0(0) -> 0
00() -> 0
eq00(0, 0) -> 1
eq01(0, 0) -> 1
01() -> 1
01() -> 2
S1(2) -> 1

(5) RelTrsToDecreasingLoopProblemProof (LOWER BOUND(ID))
Transformed a relative TRS into a decreasing-loop problem.

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).


The TRS R consists of the following rules:

   eq0(S(x'), S(x)) -> eq0(x', x)
   eq0(S(x), 0) -> 0
   eq0(0, S(x)) -> 0
   eq0(0, 0) -> S(0)

S is empty.

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

The rewrite sequence

eq0(S(x'), S(x)) ->^+ eq0(x', x)

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

The pumping substitution is [x' / S(x'), x / S(x)].

The result substitution is [ ].
