Abstract

We are proposing two greedy and a new linear programming based approximation algorithm for the total positive influence dominat- ing set problem in weighted networks. Applications of this problem in weighted settings include finding: a minimum cost set of nodes to broad- cast a message in social networks, such that each node has majority of neighbours broadcasting that message; a maximum trusted set in bitcoin network; an optimal set of hosts when running distributed apps etc. Ex- tensive experiments on different generated and real networks highlight advantages and potential issues for each algorithm.
