On the family of 0/1-polytopes with NP-complete non-adjacency relation
نویسنده
چکیده
In 1995 T. Matsui considered a special family 0/1-polytopes for which the problem of recognizing the non-adjacency of two arbitrary vertices is NP-complete. In 2012 the author of this paper established that all the polytopes of this family are present as faces in the polytopes associated with the following NP-complete problems: the traveling salesman problem, the 3-satisfiability problem, the knapsack problem, the set covering problem, the partial ordering problem, the cube subgraph problem, and some others. In particular, it follows that for these families the non-adjacency relation is also NP-complete. On the other hand, it is known that the vertex adjacency criterion is polynomial for polytopes of the following NP-complete problems: the maximum independent set problem, the set packing and the set partitioning problem, the three-index assignment problem. It is shown that none of the polytopes of the above-mentioned special family (with the exception of a one-dimensional segment) can be the face of polytopes associated with the problems of the maximum independent set, of a set packing and partitioning, and of 3-assignments.

NP-Completeness of Non-Adjacency Relations on Some 0-1 Polytopes
In this paper, we discuss the adjacency structures of some classes of 0-1 polytopes including knapsack polytopes, set covering polytopes and 0-1 polytopes represented by complete sets of implicants. We show that for each class of 0-1 polytope, non-adjacency test problems are NP-complete. For equality constrained knapsack polytopes, we can solve adjacency test problems in pseudo polynomial time.
متن کاملOn the Graph of the Pedigree Polytope
Pedigree polytopes are extensions of the classical Symmetric Traveling Salesman Problem polytopes whose graphs (1-skeletons) contain the TSP polytope graphs as spanning subgraphs. While deciding adjacency of vertices in TSP polytopes is coNP-complete, Arthanari has given a combinatorial (polynomially decidable) characterization of adjacency in Pedigree polytopes. Based on this characterization,...
متن کاملWeak order polytopes
The weak order polytope P n WO is the polytope in R n(n?1) whose ver-tices correspond to the members of the family of reeexive weak orders on f1; 2 : : : ; ng when each coordinate of R n(n?1) is associated with a diierent ordered pair (i; j) of distinct points in f1; 2; : : : ; ng. The vertex w that corresponds to weak order W has w (i;j) = 1 if i-j in W and has w (i;j) = 0 otherwise, with P n ...
متن کاملCharacterization of the Vertices and Extreme Directions of the Negative Cycles Polyhedron and Hardness of Generating Vertices of 0/1-Polyhedra
Given a graph G = (V, E) and a weight function on the edges w : E 7→ R, we consider the polyhedron P (G, w) of negative-weight flows on G, and get a complete characterization of the vertices and extreme directions of P (G, w). As a corollary, we show that, unless P = NP , there is no output polynomial-time algorithm to generate all the vertices of a 0/1-polyhedron. This strengthens the NP-hardn...
متن کاملSimple Extensions of Polytopes
We introduce the simple extension complexity of a polytope P as the smallest number of facets of any simple (i.e., non-degenerate in the sense of linear programming) polytope which can be projected onto P . We devise a combinatorial method to establish lower bounds on the simple extension complexity and show for several polytopes that they have large simple extension complexities. These example...
