... precise the bounds for the interlace polynomial C and its specializations. Theorem 23 is actually a corollary of Theorem 31. Proof of Theorem 23: For each k, for every graph G with n vertices and of ... constant. The computation time is bounded by 2n · c G · p max · | Φ |, where p max is the maximum value of p in the rules of Theorem 28 (2), and c G bounds the cost...
