(1) DecreasingLoopProof (EQUIVALENT transformation)
The following loop(s) give(s) rise to the lower bound Ω(2n):
The rewrite sequence
prod(cons(1(x13789_2), l)) →+ +(0(*(x13789_2, prod(l))), prod(l))
gives rise to a decreasing loop by considering the right hand sides subterm at position [0,0,1].
The pumping substitution is [l / cons(1(x13789_2), l)].
The result substitution is [ ].
