      Approximate Equilibria and Ball Fusion 

      Koutsoupias, Elias; Mavronicolas, Marios; Spirakis, Paul G. (2003)
      We consider selfish routing over a network consisting of m parallel links through which n selfish users route their traffic trying to minimize their own expected latency. We study the class of mixed strategies in which the ...

      Characterization of the Optimal Disturbance Attenuation for Nonlinear Stochastic Uncertain Systems 

      Charalambous, Charalambos D.; Rezaei, F.; Djouadi, S. M. (2003)
      This paper is concerned with an abstract formulation of stochastic optimal control systems, in which uncertainty is described by a relative entropy constraint between the nominal measure and the uncertain measure, while ...

      Competitive Strategy : Options and Games 

      Chevalier-Roignant, Benoit; Trigeorgis, Lenos (The MIT Press, 2011)
      Corporate managers who face both strategic uncertainty and market uncertainty confront a classic trade-off between commitment and flexibility. They can stake a claim by making a large capital investment today, influencing ...

      The complexity of decision problems about nash equilibria in win-lose games 

      Bilò, Vittorio; Mavronicolas, Marios (2012)
      We revisit the complexity of deciding, given a (finite) strategic game, whether Nash equilibria with certain natural properties exist

      Complexity of rational and irrational nash equilibria 

      Bilò, Vittorio; Mavronicolas, Marios (2014)
      We introduce two new natural decision problems, denoted as ∃ RATIONAL NASH and ∃ IRRATIONAL NASH, pertinent to the rationality and irrationality, respectively, of Nash equilibria for (finite) strategic games. These problems ...

      Computing Nash equilibria for scheduling on restricted parallel links 

      Gairing, M.; Lücking, T.; Mavronicolas, Marios; Monien, Burkhard (2010)
      We consider the problem of routing nusers on m parallel links under the restriction that each user may only be routed on a link from a certain set of allowed links for the user. So, this problem is equivalent to the ...

      Congestion games with player-specific constants 

      Mavronicolas, Marios; Milchtaich, I.; Monien, Burkhard; Tiemann, K. (2007)
      We consider a special case of weighted congestion games with player-specific latency functions where each player uses for each particular resource a fixed (non-decreasing) delay function together with a player-specific ...
