However,they also allow rapid dissemination of misinformation causing negative impacts tousers. With a source of misinformation, the longer the misinformation spreads, thegreater the number of affected users will be. Therefore, it is necessary to preventthe spread of misinformation in a specific time period. In this paper, we proposemaximizing misinformation restriction (MMR) problem with the purpose of finding aset of nodes whose removal from a social network maximizes the influence reductionfrom the source of misinformation within time and budget constraints. We demonstratethat theMMRproblem is NP-hard even in the case where the network is a rooted tree date: 2018-02 type: Article type: PeerReviewed identifier: Pham, Canh V. and Thai, My T. and Duong, Hieu V. and Bui, Bao Q. and Hoang, Xuan Huan (2018) Maximizing misinformation restriction within time and budget constraints.
