For every fixed graph H, we determine the H-covering number of K n , for all n>n 0 (H ). We prove that if h is the number of edges of H, and gcd(H )=d is the greatest common divisor of the degrees of H, then there exists n 0 =n 0 (H ), such that for all n>n 0 , Our main tool in proving this result
In this paper, we present the implementation of a branch-and-cut algorithm for solving Steiner tree problems in graphs. Our algorithm is based on an integer programming formulation for directed graphs and comprises preprocessing, separation algorithms, and primal heuristics. We are able to solve nea
