A Time-Optimal Solution for the Path Cover Problem on Cographs

چکیده
We show that the notoriously difficult problem of finding and reporting the smallest number of vertex-disjoint paths that cover the vertices of a graph can be solved timeand work-optimally for cographs. Our algorithm solves this problem in O(log n) time using n log n processors on the EREW-PRAM for an n-vertex cograph G represented by its cotree.

An optimal parallel solution for the path cover problem on P4-sparse graphs
Nakano et al. in [20] presented a timeand work-optimal algorithm for finding the smallest number of vertex-disjoint paths that cover the vertices of a cograph and left open the problem of applying their technique into other classes of graphs. Motivated by this issue we generalize their technique and apply it to the class of P4-sparse graphs, which forms a proper superclass of cographs. We show ...
متن کاملA linear-time algorithm for the k-fixed-endpoint path cover problem on cographs
In this paper,we study a variant of thepath cover problem, namely, the k -fixed-endpoint path cover problem. Given a graph G and a subset T of k vertices of V (G), a k fixed-endpoint path cover of G with respect to T is a set of vertex-disjoint paths P that covers the vertices of G such that the k vertices ofT are all endpoints of the paths inP . The k -fixed-endpoint path cover problem is to f...
متن کاملA Linear-Time Algorithm for the Terminal Path Cover Problem in Cographs
Let G = (V,E) be a graph with vertex set V and edge set E and let T be a subset of V . A terminal path cover PC of G with respect to T is a set of pairwise vertex-disjoint paths of G, such that all vertices of G are visited by exactly one path of PC and all vertices in T are end vertices of paths in PC. The terminal path cover problem is to find a terminal path cover of G of minimum cardinality...
متن کاملNear-Minimum-Time Motion Planning of Manipulators along Specified Path
The large amount of computation necessary for obtaining time optimal solution for moving a manipulator on specified path has made it impossible to introduce an on line time optimal control algorithm. Most of this computational burden is due to calculation of switching points. In this paper a learning algorithm is proposed for finding the switching points. The method, which can be used for both ...
متن کاملPartial and Perfect Path Covers of Cographs
A set P of disjoint paths in a graph G is called a (complete) path cover of G if every vertex of G belongs to one of the paths in P. A path cover of any subgraph of G is called a partial path cover of G. For xed k > 0, a k-blanket of graph G is a partial path cover P of G, consisting of exactly k paths, that maximizes the size of the subgraph covered by P. A k-core of graph G is a partial path ...
