Designing Telecommunication Networks for Survivability
January 1, 2013 ... Network survivability is a vital issue in the design of telecommunication networks. A survivable network should continue carrying the traffic it is designed for via alternate paths under any link failure (for example, a fiber cut). The optimal...

Distributed Welfare Games
January 1, 2013 ... Game-theoretic tools are becoming a popular design choice for distributed resource allocation algorithms. A central component of this design choice is the assignment of utility functions to the individual agents. The goal is to assign each agent...

Portfolio Optimization and Gambling
January 1, 2013 ... Generally speaking, risk-averse agents do not accept fair gambles because doing so reduces their expected utility. In "Risk Aversion, Indivisible Timing Options, and Gambling," V. Henderson and D. Hobson show that this conclusion can change if...

January 1, 2013 ... In making critical business decisions, managers often rely on information gleaned from various data sources. Errors in data values at these sources may lead to costly errors in business decisions. Today's managers must, therefore, have a good...

Design of Survivable Networks Using Three- and Four-Partition Facets
January 1, 2013 ... This paper considers the problem of designing a multicommodity network with single facility type subject to the requirement that under failure of any single edge, the network should permit a feasible flow of all traffic. We study the polyhedral...
