摘要: This paper considers problems of fault-tolerant information diffusion in a network with cost function. We show that the problem determining minimum necessary to perform gossiping among given set participants is NP-hard and give approximate (with respect cost) algorithms. also analyze communication time complexity Finally, we an optimal broadcasting algorithm apply our results atomic commitment problem.
