(1) DecreasingLoopProof (EQUIVALENT transformation)
The following loop(s) give(s) rise to the lower bound Ω(n1):
The rewrite sequence
intersect'ii'in(Xs, cons(X0, Ys)) →+ u'1'1(intersect'ii'in(Xs, Ys))
gives rise to a decreasing loop by considering the right hand sides subterm at position [0].
The pumping substitution is [Ys / cons(X0, Ys)].
The result substitution is [ ].
