Minimum Weighted Feedback Vertex Set on Diamonds
Given a vertex weighted graph G, a minimum Weighted Feedback Vertex Set (MWFVS) is a subset F ⊆ V of vertices of minimum weight such that each cycle in G contains at least one vertex in F . The MWFVS on general graph is known to be NP-hard. In this paper we introduce a new class of graphs, namely the diamond graphs, and give a linear time algorithm to solve MWFVS on it. We will discuss, moreove...
متن کاملA linear time algorithm for the minimum Weighted Feedback Vertex Set on diamonds
Given an undirected and vertex weighted graph G, the Weighted Feedback Vertex Problem (WFVP) consists in finding a subset F ⊆ V of vertices of minimum weight such that each cycle in G contains at least one vertex in F . The WFVP on general graphs is known to be NP-hard. In this paper we introduce a new class of graphs, namely the diamond graphs, and give a linear time algorithm to
متن کاملA Tabu Search Heuristic Based on k-Diamonds for the Weighted Feedback Vertex Set Problem
Given an undirected and vertex weighted graph G = (V,E,w), the Weighted Feedback Vertex Problem (WFVP) consists of finding a subset F ⊆ V of vertices of minimum weight such that each cycle in G contains at least one vertex in F . The WFVP on general graphs is known to be NP-hard and to be polynomially solvable on some special classes of graphs (e.g., interval graphs, co-comparability graphs, di...
متن کامل9.2 Minimum Feedback Vertex Set
Roughly speaking, the local ratio method works iteratively, and in each iteration it breaks a suitable structure (the local structure) to solve from the residual structure in that iteration. Typically the local structure is an instance that is very easy to solve. The main claim that is required is that the solution to the local structure can be patched with the solution from the next iteration,...
متن کاملMinimum feedback vertex set and acyclic coloring
In the feedback vertex set problem, the aim is to minimize, in a connected graph G = (V ,E), the cardinality of the set V (G)⊆ V , whose removal induces an acyclic subgraph. In this paper, we show an interesting relationship between the minimum feedback vertex set problem and the acyclic coloring problem (which consists in coloring vertices of a graph G such that no two colors induce a cycle in...
