Exact algorithms for finding minimum transversals in rank-3 hypergraphs
نویسنده
چکیده
We present two algorithms for the problem of nding a minimum transversal in a hypergraph of rank 3, also known as the 3-Hitting Set problem. This problem is a natural extension of the vertex cover problem for ordinary graphs. The rst algorithm runs in time O(1:6538 n) for a hypergraph with n vertices, and needs polynomial space. The second algorithm uses exponential space and runs in time O(1:6316 n).

Faster Algorithms to Enumerate Hypergraph Transversals
A transversal of a hypergraph is a set of vertices intersecting each hyperedge. We design and analyze new exponential-time algorithms to enumerate all inclusion-minimal transversals of a hypergraph. For each fixed k ≥ 3, our algorithms for hypergraphs of rank k, where the rank is the maximum size of a hyperedge, outperform the previous best. This also implies improved upper bounds on the maximu...
متن کاملA New Algorithm for the Hypergraph Transversal Problem
We consider the problem of finding all minimal transversals of a hypergraph H ⊆ 2 , given by an explicit list of its hyperedges. We give a new decomposition technique for solving the problem with the following advantages: (i) Global parallelism: for certain classes of hypergraphs, e.g. hypergraphs of bounded edge size, and any given integer k, the algorithm outputs k minimal transversals of H i...
متن کاملParameterized algorithms for double hypergraph dualization with rank limitation and maximum minimal vertex cover
Motivated by the need for succinct representations of all “small” transversals (or hitting sets) of a hypergraph of fixed rank, we study the complexity of computing such a representation. Next, the existence of a minimal hitting set of at least a given size arises as a subproblem. We give one algorithm for hypergraphs of any fixed rank, and we largely improve an earlier algorithm (by H. Fernau,...

This paper presents exact solution methods for analyzing vulnerability of electric power networks to a certain kind of undetectable attacks known as false data injection attacks. We show that the problems of finding the minimum number of measurement points to be attacked undetectably reduce to minimum cut problems on hypergraphs, which admit efficient combinatorial algorithms. Experimental resu...
متن کاملAn average study of hypergraphs and their minimal transversals
In this paper, we study some average properties of hypergraphs and the average complexity of algorithms applied to hypergraphs under different probabilistic models. Our approach is both theoretical and experimental since our goal is to obtain a random model that is able to capture the real-data complexity. Starting from a model that generalizes the Erdös-Renyi model [9, 10], we obtain asymptoti...
