Approximating Dominating Set on Intersection Graphs of L-frames
We consider the Dominating Set (DS) problem on the intersection graphs of geometric objects. Surprisingly, for simple and widely used objects such as rectangles, the problem is NP-hard even when all the rectangles are “anchored” at a line with slope -1. It is easy to see that for the anchored rectangles, the problem reduces to one with even simpler objects: L-frames. An Lframe is the union of a...
متن کاملApproximating the Minimum Independent Dominating Set in Perturbed Graphs
We investigate the minimum independent dominating set in perturbed graphs g(G, p) of input graph G = (V,E), obtained by negating the existence of edges independently with a probability p > 0. The minimum independent dominating set (MIDS) problem does not admit a polynomial running time approximation algorithm with worst-case performance ratio of n1− for any > 0. We prove that the size of the mi...
متن کاملThe Dominating Set Problem in Geometric Intersection Graphs
We study the parameterized complexity of dominating sets in geometric intersection graphs. In one dimension, we investigate intersection graphs induced by translates of a fixed pattern Q that consists of a finite number of intervals and a finite number of isolated points. We prove that Dominating Set on such intersection graphs is polynomially solvable whenever Q contains at least one interval,...
متن کاملDominating Set on Bipartite Graphs
Finding a dominating set of minimum cardinality is an NP-hard graph problem, even when the graph is bipartite. In this paper we are interested in solving the problem on graphs having a large independent set. Given a graph G with an independent set of size z, we show that the problem can be solved in time O∗(2n−z), where n is the number of vertices of G. As a consequence, our algorithm is able t...
متن کاملOn the Parameterized Complexity of Approximating Dominating Set
We study the parameterized complexity of approximating the k-Dominating Set (DomSet) problem where an integer k and a graph G on n vertices are given as input, and the goal is to find a dominating set of size at most F(k) · k whenever the graph G has a dominating set of size k. When such an algorithm runs in time T(k) · poly(n) (i.e., FPT-time) for some computable function T, it is said to be a...
