(5) DecreasingLoopProof (EQUIVALENT transformation)
The following loop(s) give(s) rise to the lower bound Ω(n1):
The rewrite sequence
a__and(true, and(true, X211_4)) →+ a__and(true, X211_4)
gives rise to a decreasing loop by considering the right hand sides subterm at position [].
The pumping substitution is [X211_4 / and(true, X211_4)].
The result substitution is [ ].
