Computer communications software is becoming increasingly important, as a result of the increasing deployment and use of computer networks. Stringent requirements of real-time processing, efciency, reliability, and inter-operability make design and development of such software extremely challenging. The development typically starts by identifying the services to be provided. A service is de ned...

E ective communication among agents in large teams is crucial because the members share a common goal but only have a partial views of the environment. Information sharing is di cult in a large team because, a team member may have a piece of valuable information but not know who needs the information, since it is infeasible to know what each other agent is doing. Although much related work has ...

is paper proposes a new approach to the problem of equilibrium selection in repeated games with transfers, by supposing that in each period the players bargain over how to play. Although the bargaining phase is cheap talk (which follows a generalized alternating-offer protocol), sharp predictions arise from three axioms. Two axioms allow the players to meaningfully discuss whether to deviate f...

The large neighborhood search (LNS) framework introduced by Shaw [11] provides a powerful hybridization of Local Search (LS) and Constraint Programming (CP). The idea of LNS is to combine the expressiveness of CP and the efciency of Local Search (LS) without requiring any meta-heuristic. LNS consists in improving a best-so-far solution by iteratively relaxing it and optimizing this solution usi...
