Runtime Complexity TRS:
The TRS R consists of the following rules:
f(true, x, y, z) → f(and(gt(x, y), gt(x, z)), x, s(y), z)
f(true, x, y, z) → f(and(gt(x, y), gt(x, z)), x, y, s(z))
gt(0, v) → false
gt(s(u), 0) → true
gt(s(u), s(v)) → gt(u, v)
and(x, true) → x
and(x, false) → false
Rewrite Strategy: FULL
(1) CpxTrsToCpxRelTrsProof (BOTH BOUNDS(ID, ID) transformation)
Transformed TRS to relative TRS where S is empty.
(2) Obligation:
Runtime Complexity Relative TRS:
The TRS R consists of the following rules:
f(true, x, y, z) → f(and(gt(x, y), gt(x, z)), x, s(y), z)
f(true, x, y, z) → f(and(gt(x, y), gt(x, z)), x, y, s(z))
gt(0, v) → false
gt(s(u), 0) → true
gt(s(u), s(v)) → gt(u, v)
and(x, true) → x
and(x, false) → false
S is empty.

(3) DecreasingLoopProof (EQUIVALENT transformation)
The following loop(s) give(s) rise to the lower bound Ω(n1):
The rewrite sequence
gt(s(u), s(v)) →+ gt(u, v)
gives rise to a decreasing loop by considering the right hand sides subterm at position [].
The pumping substitution is [u / s(u), v / s(v)].
The result substitution is [ ].
