چکیده
We consider the problem of maintaining a large matching and a small vertex cover in a dynamically changing graph. Each update to the graph is either an edge deletion or an edge insertion. We give the first randomized data structure that simultaneously achieves a constant approximation factor and handles a sequence of K updates in K · polylog(n) time, where n is the number of vertices in the graph. Previous data structures require a polynomial amount of computation per update.

Bounding cochordal cover number of graphs via vertex stretching
It is shown that when a special vertex stretching is applied to a graph, the cochordal cover number of the graph increases exactly by one, as it happens to its induced matching number and (Castelnuovo-Mumford) regularity. As a consequence, it is shown that the induced matching number and cochordal cover number of a special vertex stretching of a graph G are equal provided G is well-covered bipa...

متن کامل2 Edmonds ’ Algorithm for Maximum Matching 3 Minimum Edge Covers
Any set of vertices V ′ with {{u, v} : u ∈ V ′} (smallest or otherwise) is called a vertex cover of the graph. Intuitively, a cover is a dusting of vertices so that every edge in the graph is “covered” by some vertex, although you might also say that each edge is “hit” by some vertex. Note that vertex cover is a minimization problem, with the goal to find a vertex cover that is as small as poss...
متن کاملMatching Integral Graphs of Small Order
In this paper, we study matching integral graphs of small order. A graph is called matching integral if the zeros of its matching polynomial are all integers. Matching integral graphs were first studied by Akbari, Khalashi, etc. They characterized all traceable graphs which are matching integral. They studied matching integral regular graphs. Furthermore, it has been shown that there is no matc...
