Center node: "egalitarian deliberative decision making"
  Abstract: We study a scenario in which an agent population wishes to identify a majority-supported proposal to change the status quo, where proposals are elements of an abstract space. In our deliberation process agents form coalitions around proposals that they prefer over the status quo, and can then join forces to create larger coalitions by merging two coalitions around a new proposal, possibly leaving dissenting agents behind. We identify a class of metric spaces, which includes all Euclidean spaces, for which the deliberation process is guaranteed to result in \emph{success}: Deliberation will terminate with a majority coalition, as long as a majority-supported proposal exists. We then consider a more general proposal space where deliberation might not be successful. For such a setting we study sufficient conditions on the type of deliberation that can again guarantee success. We complement our analysis with a centralized dynamic programming algorithm to identify the most-supported proposal.

Question: Please tell me which class the center node belongs to. The 40 classes are: cs.NA(Numerical Analysis), cs.MM(Multimedia), cs.LO(Logic in Computer Science), cs.CY(Computers and Society), cs.CR(Cryptography and Security), cs.DC(Distributed, Parallel, and Cluster Computing), cs.HC(Human-Computer Interaction), cs.CE(Computational Engineering, Finance, and Science), cs.NI(Networking and Internet Architecture), cs.CC(Computational Complexity), cs.AI(Artificial Intelligence), cs.MA(Multiagent Systems), cs.GL(General Literature), cs.NE(Neural and Evolutionary Computing), cs.SC(Symbolic Computation), cs.AR(Hardware Architecture), cs.CV(Computer Vision and Pattern Recognition), cs.GR(Graphics), cs.ET(Emerging Technologies), cs.SY(Systems and Control), cs.CG(Computational Geometry), cs.OH(Other Computer Science), cs.PL(Programming Languages), cs.SE(Software Engineering), cs.LG(Machine Learning), cs.SD(Sound), cs.SI(Social and Information Networks), cs.RO(Robotics), cs.IT(Information Theory), cs.PF(Performance), cs.CL(Computation and Language), cs.IR(Information Retrieval), cs.MS(Mathematical Software), cs.FL(Formal Languages and Automata Theory), cs.DS(Data Structures and Algorithms), cs.OS(Operating Systems), cs.GT(Computer Science and Game Theory), cs.DB(Databases), cs.DL(Digital Libraries), cs.DM(Discrete Mathematics). Directly output the class name.
