Sensitivity of the Performance of a Simple Exchange Model to its Topology
Vitus J. Leung, Randall A. LaViolette
We study a simple exchange model in which price is fixed and the amount of a good transferred between actors depends only on the actors' respective budgets and the existence of a l…
Emergence of Price Divergence in a Model Short-Term Electric Power Market
Randall A. LaViolette, Lory A. Ellebracht, Kevin L. Stamber +2
A minimal model of a market of myopic non-cooperative agents who trade bilaterally with random bids reproduces qualitative features of short-term electric power markets, such as th…
Tolerating the Community Detection Resolution Limit with Edge Weighting
Jonathan W. Berry, Bruce Hendrickson, Randall A. LaViolette +1
Communities of vertices within a giant network such as the World-Wide Web are likely to be vastly smaller than the network itself. However, Fortunato and Barthélemy have proved tha…
Community Detection via Facility Location
Jonathan W. Berry, Bruce Hendrickson, Randall A. LaViolette +2
In this paper we apply theoretical and practical results from facility location theory to the problem of community detection in networks. The result is an algorithm that computes b…
Limits on Relief through Constrained Exchange on Random Graphs
Randall A. LaViolette, Lory A. Ellebracht, Charles J. Gieseler
Agents are represented by nodes on a random graph (e.g., small world or truncated power law). Each agent is endowed with a zero-mean random value that may be either positive or neg…
Parameters Affecting the Resilience of Scale-Free Networks to Random Failures
Hamilton Link, Randall A. LaViolette, Jared Saia +1
It is commonly believed that scale-free networks are robust to massive numbers of random node deletions. For example, Cohen et al. study scale-free networks including some which ap…
