We ask, When does a graph G have a subgraph I' such that the vertices of odd degree in form a specified set S C V ( G ) , such that G -E(T) is connected? If such a subgraph can be found for a suitable choice of S, then this can be applied to problems such as finding a spanning eulerian subgraph of G
The k-MAXCUT problem for undirected graphs C = (V, E ) consists of finding a partition V = V , U . . . U V, such that the number of edges with endpoints in two different sets V, is maximized. We offer a new approach to this problem by showing that the combinatorial notion of block designs can be use
