On Finding a Minimum Dominating Set in a Tournament
The problem of nding a minimum dominating set in a tournament can be solved in njO(log n) time. It is shown that if this problem has a polynomial-time algorithm then for every constant C, there is also a polynomial-time algorithm for the satissability problem of boolean formulas in conjunctive normal form with m clauses and C log j2m variables. On the other hand, the problem can be reduced in p...

متن کاملA Branch-and-Reduce Algorithm for Finding a Minimum Independent Dominating Set in Graphs
A dominating set D of a graph G = (V,E) is a subset of vertices such that every vertex in V \D has at least one neighbour in D. Moreover if D is an independent set, i.e. no vertices in D are pairwise adjacent, then D is said to be an independent dominating set. Finding a minimum independent dominating set in a graph is an NP-hard problem. We give an algorithm computing a minimum independent dom...
متن کاملMinimum Dominating Set for a Point Set in $\IR^2$
In this article, we consider the problem of computing minimum dominating set for a given set S of n points in R. Here the objective is to find a minimum cardinality subset S of S such that the union of the unit radius disks centered at the points in S covers all the points in S. We first propose a simple 4-factor and 3-factor approximation algorithms in O(n log n) and O(n logn) time respectivel...
متن کاملAn independent dominating set in the complement of a minimum dominating set of a tree
We prove that for every tree T of order at least 2 and every minimum dominating set D of T which contains at most one endvertex of T , there is an independent dominating set I of T which is disjoint from D. This confirms a recent conjecture of Johnson, Prier, and Walsh.
