### (1) DecreasingLoopProof (EQUIVALENT transformation)

The following loop(s) give(s) rise to the lower bound Ω(n1):
The rewrite sequence
max(N(L(s(x)), L(s(y)))) →+ s(max(N(L(x), L(y))))
gives rise to a decreasing loop by considering the right hand sides subterm at position [0].
The pumping substitution is [x / s(x), y / s(y)].
The result substitution is [ ].

Proved the following rewrite lemma:

Induction Base:
max(gen_L:N4_0(+(1, 0))) →RΩ(1)
0'

Induction Step:
max(gen_L:N4_0(+(1, +(n6_0, 1)))) →RΩ(1)
max(N(L(0'), L(max(N(L(0'), gen_L:N4_0(n6_0)))))) →IH
