A subset S of V is called a k-connected dominating set if S is a dominating set and the induced subgraph has at most k components. The k-connected domination n
In this paper, a new algorithm relaxation-strategy-based modification branch-and-bound algorithm is developed for a type of solving the minimum cost transportat
