Coreness of Cooperative Games with Truncated Submodular Profit Functions
Wei Chen, Xiaohan Shan, Xiaoming Sun +1
Coreness represents solution concepts related to core in cooperative games, which captures the stability of players. Motivated by the scale effect in social networks, economics and…
Higher order monotonicity and submodularity of influence in social networks: from local to global
Wei Chen, Qiang Li, Xiaohan Shan +2
Kempe, Kleinberg and Tardos (KKT) proposed the following conjecture about the general threshold model in social networks: local monotonicity and submodularity imply global monotoni…
Cumulative Activation in Social Networks
Xiaohan Shan, Wei Chen, Qiang Li +2
Most studies on influence maximization focus on one-shot propagation, i.e. the influence is propagated from seed users only once following a probabilistic diffusion model and users…
The Least-core and Nucleolus of Path Cooperative Games
Qizhi Fang, Bo Li, Xiaohan Shan +1
Cooperative games provide an appropriate framework for fair and stable profit distribution in multiagent systems. In this paper, we study the algorithmic issues on path cooperative…
