Improved Upper Bounds for Partial Vertex Cover
نویسندگان
چکیده
The Partial Vertex Cover problem is to decide whether a graph contains at most k nodes covering at least t edges. We present deterministic and randomized algorithms with run times of O(1.396) and O(1.2993), respectively. For graphs of maximum degree three, we show how to solve this problem in O(1.26) steps. Finally, we give an O(3) algorithm for Exact Partial Vertex Cover, which asks for at most k nodes covering exactly t edges.

Upper Bounds for Vertex Cover Further Improved
The problem instance of Vertex Cover consists of an undirected graph G = (V, E) and a positive integer k, the question is whether there exists a subset C ⊆ V of vertices such that each edge in E has at least one of its endpoints in C with |C| ≤ k. We improve two recent worst case upper bounds for Vertex Cover. First, Balasubramanian et al. showed that Vertex Cover can be solved in time O(kn + 1...
متن کاملImproved Parameterized Upper Bounds for Vertex Cover
This paper presents an O(1.2738 + kn)-time polynomialspace parameterized algorithm for Vertex Cover improving the previous O(1.286+kn)-time polynomial-space upper bound by Chen, Kanj, and Jia. The algorithm also improves the O(1.2745k+kn)-time exponentialspace upper bound for the problem by Chandran and Grandoni.
متن کاملOn the k-path vertex cover of some graph products
A subset S of vertices of a graph G is called a k-path vertex cover if every path of order k in G contains at least one vertex from S. Denote by ψk(G) the minimum cardinality of a k-path vertex cover in G. In this paper improved lower and upper bounds for ψk of the Cartesian and the direct product of paths are derived. It is shown that for ψ3 those bounds are tight. For the lexicographic produc...

متن کاملAlgorithmic Meta-Theorems for Graphs of Bounded Vertex Cover
Possibly the most famous algorithmic meta-theorem is Courcelle’s theorem, which states that all MSO-expressible graph properties are decidable in linear time for graphs of bounded treewidth. Unfortunately, the running time’s dependence on the MSO formula describing the problem is in general a tower of exponentials of unbounded height, and there exist lower bounds proving that this cannot be imp...
