Domination games and treewidth

چکیده
The r-domination search game on graphs is a game-theoretical approach to several graph and hypergraph parameters including treewidth and hypertree width. The task is to identify the minimum number of cops sufficient to catch the visible and very fast robber. To catch the robber, at least one of the cops should be within at most r edges from him. We give a constant factor approximation algorithm that for every fixed r and graph H , computes the minimum number of cops required to capture the robber in the r-domination game on graphs excluding H as a minor.

ROMAN DOMINATION: A Parameterized Perspective
We analyze the graph-theoretic formalization of Roman domination, dating back to the military strategy of Emperor Constantine, from a parameterized perspective. More specifically, we prove that this problem is W[2]-complete for general graphs. However, parameterized algorithms are presented for graphs of bounded treewidth and for planar graphs. Moreover, it is shown that a parametric dual of Ro...
متن کامل(Total) Vector Domination for Graphs with Bounded Branchwidth
Given a graph G = (V, E) of order n and an n-dimensional non-negative vector d = (d(1), d(2), . . . , d(n)), called demand vector, the vector domination (resp., total vector domination) is the problem of finding a minimum S ⊆ V such that every vertex v in V \S (resp., in V ) has at least d(v) neighbors in S. The (total) vector domination is a generalization of many dominating set type problems,...
متن کاملDominating Sets and Local Treewidth
It is known that the treewidth of a planar graph with a dominating set of size d is O( √ d) and this fact is used as the basis for several fixed parameter algorithms on planar graphs. An interesting question motivating our study is if similar bounds can be obtained for larger minor closed graph families. We say that a graph family F has the domination-treewidth property if there is some functio...
متن کاملThe tractability frontier of well-designed SPARQL queries
We study the complexity of query evaluation of SPARQL queries. We focus on the fundamental fragment of welldesigned SPARQL restricted to the AND, OPTIONAL and UNION operators. Our main result is a structural characterisation of the classes of well-designed queries that can be evaluated in polynomial time. In particular, we introduce a new notion of width called domination width, which relies on...
متن کاملA Fixed-Parameter Algorithm for Max Edge Domination
In a graph, an edge is said to dominate itself and its adjacent edges. Given an undirected and edge-weighted graph G = (V,E) and an integer k, Max Edge Domination problem (MaxED) is to find a subset K ⊆ E with cardinality at most k such that total weight of edges dominated by K is maximized. MaxED is NP-hard due to the NP-hardness of the minimum edge dominating set problem. In this paper, we pr...
