چکیده
A connected domination set of a graph is a set of vertices such that every vertex not in is adjacent to and the induced subgraph of is connected. The minimum connected domination set of a graph is the connected domination set with the minimum number of vertices. In this paper, we propose parallel algorithms for finding the minimum connected domination set of interval graphs and circular-arc graphs. Our algorithms run in time algorithm using processors while the intervals and arcs are given in sorted order. Our algorithms are on the EREW PRAM model. Key-Words: Connected Domination Set, Interval Graph, Circular-arc Graph.

Efficient Algorithms for the Domination Problems on Interval and Circular-Arc Graphs
This paper first presents a unified approach to design efficient algorithms for the weighted domination problem and its three variants, i.e., the weighted independent, connected, and total domination problems, on interval graphs. Given an interval model with endpoints sorted, these algorithms run in time O(n) or O(n log logn) where n is the number of vertices. The results are then extended to s...
متن کاملPaired domination on interval and circular-arc graphs
We study the paired-domination problem on interval graphs and circular-arc graphs. Given an interval model with endpoints sorted, we give an O(m + n) time algorithm to solve the paired-domination problem on interval graphs. The result is extended to solve the paired-domination problem on circular-arc graphs in O(m(m+ n)) time. MSC: 05C69, 05C85, 68Q25, 68R10, 68W05
متن کاملLinear-Time Algorithms for the Paired-Domination Problem in Interval Graphs and Circular-Arc Graphs
In a graph G, a vertex subset S ⊆ V (G) is said to be a dominating set of G if every vertex not in S is adjacent to a vertex in S. A dominating set S of a graph G is called a paired-dominating set if the induced subgraph G[S] contains a perfect matching. The paired-domination problem involves finding a smallest paired-dominating set of G. Given an intersection model of an interval graph G with ...
متن کاملSome Optimal Parallel Algorithms on Interval and Circular-arc Graphs
In this paper, we consider some shortest path related problems on interval and circular-arc graphs. For the all-pair shortest path query problem on interval and circular-arc graphs, instead of using the sophisticated technique, we propose simple parallel algorithms using only the parallel prefix and suffix computations and the Euler tour technique. Our preprocessing algorithms run in O(log n) t...
