Exponential Communication Separations between Notions of Selfishness [article]

Aviad Rubinstein, Raghuvansh R. Saxena, Clayton Thomas, S. Mathew Weinberg, Junyao Zhao
2021 arXiv   pre-print
We show exponential separations between all three of these quantities, already for just two players.  ...  That is, we first construct an f such that f can be implemented in communication c, but any EPIC implementation of f (with any choice of payments) requires communication exp(c).  ...  Moreover, there is an exponential separation between the communication complexity for computing f and the communication complexity of any EPIC implementation of f , i.e., CC(f ) = O(log n) CC EP IC (f  ...

2011 arXiv   pre-print
We show a super-exponential separation between monotone and non-monotone computation in the non-commutative model, and thus provide a strong solution to Nisan's question Nis1991 in algebraic complexity  ...  communication complexity and the logarithm of the rank of the communication tensor.  ...  Algebraic Complexity Valiant [Val80] shows an exponential separation between monotone and non-monotone computation in terms of algebraic circuit complexity.  ...

Dynamic Traffic Models in Transportation Science (Dagstuhl Seminar 18102)

Roberto Cominetti, Tobias Harks, Carolina Osorio, Britta Peis, Michael Wagner
2018 Dagstuhl Reports  
The starting point of the seminar was the observation that there is a trend in the transportation community (science as well as industry) to base such predictions on complex computer-based simulations  ...  that are capable of resolving many elements of a real transportation system.  ...  Reinterpreting this process as a game between bidders, we introduce the notion of pacing equilibrium, and prove that they are always guaranteed to exist.  ...

Each social group has a particular intricate arrangement of ties between its members, and our understanding of that group depends on which of those ties we emphasize, be it blood relations, geographic  ...  But there can also be a big difference between having ten friends who have no friends and having ten friends who have ten friends each.  ...  And we can gain a much better understanding of human behaviour if we give up the notion of Homo economicus, the selfish, rational, profit maximizer, for the new notion of Homo dictyous, the connected,  ...

IMPACT: Investigation of Mobile-user Patterns Across University Campuses using WLAN Trace Analysis [article]

Wei-jen Hsu, Ahmed Helmy
2005 arXiv   pre-print
We establish that number of encounters follows a biPareto distribution, while friendship indexes follow an exponential distribution.  ...  We clearly identify categories of heavy and light users. In general, users exhibit high degree of similarity over days and weeks.  ...  separation of nodes in the ER graph.  ...

A Self-Organized Clustering Scheme for Overlay Networks [chapter]

Francois Cantin, Bamba Gueye, Mohamed Ali Kaafar, Guy Leduc
2008 Lecture Notes in Computer Science  
The second variant, where nodes are selfish, aims at reducing the induced communication overhead.  ...  For better scalability and efficiency, our algorithm uses the coordinates of a subset of nodes, known by running an ICS system, as first approximations of node positions.  ...  If we consider highly-dynamic networks, the differentiation between the initial phase and the steady state may fade away.  ...

Coalition formation through learning in autonomic networks

Tao Jiang, John S. Baras
2009 2009 International Conference on Game Theory for Networks  
However, due to resource constraints, nodes are generally selfish and try to maximize their own benefit when participating in the network.  ...  The dynamics of coalition formation proceed via nodes that interact strategically and adapt their behavior to the observed behavior of others.  ...  If two members of separate coalitions decide to activate the edge between them, then the two coalitions merge into one.  ...

The Randomized Communication Complexity of Randomized Auctions [article]

Aviad Rubinstein, Junyao Zhao
2021 arXiv   pre-print
In particular, our lower bounds give the first approximation-resistant, exponential separation between communication complexity of incentivizing vs implementing a Bayesian incentive compatible social choice  ...  We study the communication complexity of incentive compatible auction-protocols between a monopolist seller and a single buyer with a combinatorial valuation function over n items.  ...  They give examples where the communication cost of selfishness is exponential, but those examples are very brittle in the sense that they rely on agents' utilities to have unbounded (or at least exponential  ...

Coordination mechanisms for decentralized parallel systems

Johanne Cohen, Daniel Cordeiro, Denis Trystram
2014 Concurrency and Computation  
We study the price that the collectivity must pay in order to allow independence to selfish, self-governing organizations, so they can choose the best schedules for their own jobs.  ...  We present a game-theoretic model for the problem and the associated coordination mechanisms developed to reduce the cost of the decentralization of the decision-making process.  ...  Using tools from algorithmic game theory, we extend the notions of independence and selfishness of each participating organization.  ...
