Thresholds for the monochromatic clique transversal game

نویسندگان

چکیده

We study a recently introduced two-person combinatorial game, the (a,b)-monochromatic clique transversal game which is played by Alice and Bob on graph G. As we observe, this equivalent to (b,a)-biased Maker–Breaker clique-hypergraph of Our main results concern threshold bias a1(G) that smallest integer such can win in (a,1)-monochromatic G if she first play. Among other results, determine possible values for disjoint union graphs, prove formula triangle-free, obtain exact a1(Cn□Cm), a1(Cn□Pm), a1(Pn□Pm) all pairs (n,m).

Parallel algorithms for generalized clique transversal problems

The K `-clique transversal problem is to locate a minimum collection of cliques of size ` in a graph G such that every maximal clique of sizè in G contains at least one member of the collection. We give an NC algorithm to solve this problem on strongly chordal graphs.

Monochromatic Clique Decompositions of Graphs

Let G be a graph whose edges are colored with k colors, and H=(H1,⋯,Hk) be a k-tuple of graphs. A monochromatic H-decomposition of G is a partition of the edge set of G such that each part is either a single edge or forms a monochromatic copy of Hi in color i, for some 1≤i≤k. Let φk(n,H) be the smallest number ϕ, such that, for every order-n graph and every k-edge-coloring, there is a monochrom...

Clique-Transversal Sets in Cubic Graphs

A clique-transversal set S of a graph G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted τc(G), is the minimum cardinality of a clique-transversal set in G. In this paper we present an upper bound and a lower bound on τc(G) for cubic graphs, and characterize the extremal cubic graphs achieving the lower bound. In addition, we present a sharp u...

On the clique-game

We study Maker/Breaker games on the edges of the complete graph, as introduced by Chvátal and Erdős. We show that in the (m : b) game played on KN , the complete graph on N vertices, Maker can achieve a Kq for q = ( m log 2 (b+1) − o(1) ) · log2 N , which partially solves an open problem by Beck. Moreover, we show that in the (1 : 1) game played on KN for a sufficiently large N , Maker can achi...

The Maximum Clique Interdiction Game

We study the two player zero-sum Stackelberg game in which the leader interdicts (removes) a limited number of vertices from the graph, and the follower searches for the maximum clique in the interdicted graph. The goal of the leader is to derive an interdiction policy which will result in the worst possible outcome for the follower. This problem has applications in many areas, such as crime de...
