On multiaccess channel with unidirectional cooperation and security constraints
2012 50th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2012We study a special case of Willems's two-user multi-access channel with partially cooperating encoders from a security perspective. This model differs from Willems's setup in the following aspects — only one encoder, Encoder 1, is allowed to conference, Encoder 2 does not transmit any message, and there is an additional passive eavesdropper from whom ...

Cooperative Solution of Constraint Satisfaction Problems
Science, 1991It is widely believed that a group of cooperating agents engaged in problem solving can solve a task faster than either a single agent or the same group of agents working in isolation from each other. Nevertheless, little is known about the quantitative improvements that result from cooperation.

Investment Constraints in Agricultural Cooperatives
2015Though horizon and portfolio problems are commonly thought to limit cooperatives’ ability to capitalize on investment opportunities, empirical inquiry into the existence of these constraints is sparse, and recent conceptual arguments suggest that the horizon problem in particular may be less severe than commonly believed.

Cooperative control under communication constraints
2008 IEEE Information Theory Workshop, 2008Understanding the role of communication in networked control systems is an important and challenging problem. In this paper we determine the communication rates required to achieve a variety of cooperative control objectives. Our results depend heavily on three information theoretic ideas: the directed data processing inequality, Slepian-Wolf coding ...

Cooperating Constraint Solvers
2000We propose a general scheme for the cooperation of different constraint solvers. On top of a uniform interface for constraint we stepwise develop reduction systems which describe the behaviour of an overall combined system. The modularity of our definitions of reduction relations at different levels allows the definition of cooperation strategies for ...

Stable Cooperative Surveillance With Information Flow Constraints
IEEE Transactions on Control Systems Technology, 2008We consider a cooperative surveillance problem for a group of autonomous air vehicles (AAVs) that periodically receives information on suspected locations of targets from a satellite and then must cooperate to decide which AAV should search for each target.

Cooperation of constraint domains in the TOY system
Proceedings of the 10th international ACM SIGPLAN conference on Principles and practice of declarative programming, 2008This paper presents a computational model for the cooperation of constraint domains, based on a generic Constraint Functional Logic Programming (CFLP) Scheme and designed to support declarative programming with functions, predicates and the cooperation of different constraint domains equipped with their respective solvers.

Nonlinear DynamicsFor servo mechanical systems, it is typically desirable to consider a series of equality and inequality constraints in the control analysis. While constraint-following control strategies based on the Udwadia–Kalaba (U–K) equation efficiently tackle ...

Playing with $\cal{TOY}$ : Constraints and Domain Cooperation
2008This paper describes TOY, an implementation of a Constraint Functional Logic Programming scheme CFLP(C), where C is a coordination domain involving the cooperation among several constraint domains D1, ..., Dn via a mediatorial domain M. This implementation follows a cooperative goal solving calculus for CFLP(C) based on lazy narrowing, invocation of ...

Cooperative ground target tracking with input constraints
2010 11th International Conference on Control Automation Robotics & Vision, 2010This paper considers the problem of cooperative target tracking with multiple unmanned aerial vehicles (UAVs) subject to input constraints. Cooperation of multiple UAVs to track a moving target can provide better performance and enhance the robustness.
