Comparing Reductions to NP-Complete Sets
Under the assumption that NP does not have p-measure 0, we investigate reductions to NP-complete sets and prove the following: (1) Adaptive reductions are more powerful than nonad...

Optimal leaf ordering of complete binary trees
Ordering a set of items so as to minimize the sum of distances between consecutive elements is a fundamental optimization problem occurring in many settings. While it is NP-hard i...

Equational approximations for tree automata completion
In this paper we deal with the verification of safety properties of infinite-state systems modeled by term-rewriting systems. An over-approximation of the set of reachable terms...

Appearance and Geometry Completion with Constrained Texture Synthesis
A novel approach for appearance and geometry completion over point-sampled geometry is presented in this paper. Based on the result of surface clustering and the given texture samp...

The Completeness of Propositional Resolution: A Simple and Constructive Proof
It is well known that the resolution method (for propositional logic) is complete. However, completeness proofs found in the literature use an argument by contradiction showing tha...
