The Complexity of Minor-Ancestral Graph Properties with Forbidden Pairsannakakis [14] showed that for any nontrivial node-hereditary graph property, the problem of given a graph, finding the size of the largest induced subgraph of the graph that has the property, is .-hard. In this paper, we completely characterize those minor-ancestral properties for which the problem

Satisfiability Thresholds beyond , −XORSATlity threshold of such systems occurs where the 2 −core has density 1. We show a similar result for random uniquely extendible constraints over 4 elements. Our results extend previous results of Dubois/Mandler for equations mod 2 and . = 3 and Connamacher/Molloy for uniquely extendible constraints o

Finding Vertex-Surjective Graph Homomorphisms host graph. The bijective and injective homomorphism problems can be formulated in terms of spanning subgraphs and subgraphs, and as such their computational complexity has been extensively studied. What about the surjective variant? Because this problem is NP-complete in general, we restrict the g

Broadcast Domination on Block Graphs in Linear Timerom a vertex . with .(.) > 0. The . problem seeks to compute a broadcast domination where the sum of the assigned values is minimized. We show that . can be solved in linear time on block graphs. For general graphs the best known algorithm runs in time .. For trees and interval graphs, linear-time a

Descriptional Complexity of Operations on Alternating and Boolean Automatate is 2. + 1. This solves an open problem stated by Fellah . (Intern. J. Computer Math. 35, 1990, 117–132). Then we examine the complexity of basic operations on languages represented by boolean and alternating finite automata. We get tight bounds for intersection and union, and for concatenation an

The Chemistry of the Non-Metalsme. This improves the previous known result for ...Our deterministric sorting relies on the notion of an approximate .-th order statistic. For this auxiliary problem, we devise a deterministic algorithm that runs in . time and produces a key (either corrupted or not) whose order rank differs from . by at most .(.).
