Reconfiguration of dominating sets

Abstract: Abstract. We explore a reconfiguration version of the dominating set problem, where a dominating set in a graph G is a set S of vertices such that each vertex is either in S or has a neighbour in S. In a reconfiguration problem, the goal is to determine whether there exists a sequence of feasible solutions connecting given feasible solutions s and t such that each pair of consecutive solutions is adjacent according to a specified adjacency relation. Two dominating sets are adjacent if one can be formed from th… Show more

“…The reconfiguration paradigm has recently been applied to a number of algorithmic problems: vertex coloring [1,2,3,4,5], list-edge coloring [7], clique, set cover, integer programming, matching, spanning tree, matroid bases [8], block puzzles [9], satisfiability [10], independent set [9,8,11], shortest paths [12,13,14], and dominating set [15]; recently also in the setting of parameterized complexity [16]. A recent survey [17] gives a good introduction to this area of research.…”

“…In contrast, the k-dominating graph can be disconnected for k = Γ(G) + 1, even for planar, bounded tree-width, or b-partite for b ≥ 3 [127]. In addition, there is an infinite family of graphs with exponential diameter for γ(G) + 1 [127].…”

“…For Γ(G) the upper domination number (the maximum cardinality of a minimal dominating set of G), the connectivity of the k-dominating graph has been shown for the following cases: In contrast, the k-dominating graph can be disconnected for k = Γ(G) + 1, even for planar, bounded tree-width, or b-partite for b ≥ 3 [126]. In addition, there is an infinite family of graphs with exponential diameter for γ(G) + 1 [126]. Under TAR, the reachability problem is PSPACE-complete even for bounded bandwidth, split graphs, planar graphs, and bipartite graphs [50], whereas linear-time algorithms have been developed for cographs, trees, and interval graphs [50].…”
