Induced matchings in asteroidal triple-f
✍ Jou-Ming Chang 📂 Article 📅 2003 🏛 Elsevier Science 🌐 English ⚖ 193 KB

An induced matching M of a graph G is a set of pairwise nonadjacent edges such that no two edges of M are joined by an edge in G. The problem of ÿnding a maximum induced matching is known to be NP-hard even for bipartite graphs of maximum degree four. In this paper, we study the maximum induced matc

Approximating the Bandwidth for Asteroid
✍ Ton Kloks; Dieter Kratsch; Haiko Müller 📂 Article 📅 1999 🏛 Elsevier Science 🌐 English ⚖ 110 KB

We show that there is an O nm algorithm to approximate the bandwidth of an AT-free graph with worst case performance ratio 2. Alternatively, at the cost of the Ž . approximation factor, we can also obtain an O m q n log n algorithm to approximate the bandwidth of an AT-free graph within a factor 4.
