In this paper, we consider a frequency assignment problem occurring in a military context. The main originality of the problem pertains to its dynamic dimension: new communications requiring frequency assignments need to be established throughout a deployment. The problem decomposes in three phases: assignment of an initial kernel of communications, dynamic assignment of new communication links...

The paper deals with simulation of congested road networks through dynamic traffic assignment models and presents a new quasi-dynamic traffic assignment model that improves realism and effectiveness of both usual static traffic assignment models and other quasi-dynamic models recently introduced in the literature, as it simulates flow progression onto the network by moving link flows according ...

the prevalent communications networks suffer from lack of spectrum and spectrum inefficiency. this has motivated researchers to develop cognitive radio (cr) as a smart and dynamic radio access promised solution. a major challenge to this new technology is how to make fair assignment of available spectrum to unlicensed users, particularly for smart grids communication. this paper introduces an i...

The major purpose of our research is to study cooperative planning for multi-agent system in time-critical environment. The RoboCup simulator league is the most interesting target for our research. Each agent of the team 11monkeys is realized as an autonomous agent that has two sets of rules, namely state dependent rules and position specified rules. We call the former dynamic role and the latt...

Clustered microarchitectures are an effective approach to reducing the penalties caused by wire delays inside a chip. Current superscalar processors have in fact a two-cluster microarchitecture with a naive code partitioning approach: integer instructions are allocated to one cluster and floating-point instructions to the other. This partitioning scheme is simple and results in no communication...

There has been considerable recent interest in the dynamic vehicle routing problem, but the complexities of this problem class have generally restricted research to myopic models. In this paper, we address the simpler dynamic assignment problem, where a resource (container, vehicle or driver) can only serve one task at a time. We propose a very general class of dynamic assignment models, and pr...

In multiagent systems, often agents need to be assigned to different roles. Multiple aspects should be taken into account for this, such as agents’ skills and constraints posed by existing assignments. In this paper, we focus on another aspect: when the agents are selfinterested, careful role assignment is necessary to make cooperative behavior an equilibrium of the repeated game. We formalize ...
