Polynomial-time algorithms from ineffective proofs [PDF]
We present a constructive procedure for extracting polynomial-time realizers from ineffective proofs of /spl Pi//sub 2//sup 0/-theorems in feasible analysis. By ineffective proof we mean a proof which involves the noncomputational principle weak Konig's lemma WKL, and by feasible analysis we mean Cook and Urquhart's system CPV/sup /spl omega// plus ...

A Polynomial-Time Algorithm for Pliable Index Coding [PDF]
In pliable index coding, we consider a server with $m$ messages and $n$ clients where each client has as side information a subset of the messages. We seek to minimize the number of broadcast transmissions, so that each client can recover any one unknown message she does not already have. Previous work has shown that the pliable index coding problem is

Polynomial Time and Parameterized Approximation Algorithms for Boxicity [PDF]
The boxicity (cubicity) of a graph G, denoted by box(G) (respectively cub(G)), is the minimum integer k such that G can be represented as the intersection graph of axis parallel boxes (cubes) in ℝk. The problem of computing boxicity (cubicity) is known to be inapproximable in polynomial time even for graph classes like bipartite, co-bipartite and split

The method of generation program code with indistinguishable functionality
The paper presents an obfuscation problem, in which indistinguishability is considered relatively to programs with distinguishable functionality. The functionality remains undisclosed owing to unknown parameters in the program’s input.

A Polynomial Time Algorithm for 3sat
By creating some new concepts and methods: checking tree, long unit path, direct contradiction unit pair, indirect contradiction unit pair, additional contradiction unit pair, 2-unit layer and 3-unit layer, redundant units, and destroying parallel pairs , we successfully transform solving a 3SAT problem to solving 2SAT problems in polynomial time. Thus

A polynomial time circle packing algorithm
A map on a surface \(S\) is a pair \((G,S)\) with \(G\) a graph which is 2-cell embedded in \(S\). A circle packing is a set of geodesic circles, with disjoint interiors, in a Riemannian surface \(S'\) of constant curvature. Connecting the midpoints of the circles with the touching points (with other circles or the same circle), one gets a graph on \(S'

A Polynomial Time Algorithm for Unidimensional Unfolding Representations
Summary: Two conditions on a collection of simple orders -- unimodality and straightness -- are necessary but not jointly sufficient for unidimensional unfolding representations. From the analysis of these conditions, a polynomial time algorithm is derived for the testing of unidimensionality and for the construction of a representation when one exists.
