ADOPT-ng: Unifying Asynchronous Distributed Optimization with Asynchronous Backtracking
This article presents an asynchronous algorithm for solving Distributed Constraint Optimization problems (DCOPs). The proposed technique unifies asynchronous backtracking (ABT) and asynchronous distributed optimization (ADOPT) where valued nogoods enable more flexible reasoning and more opportunities of communication, leading to an important speed-up. The concept of valued nogood is an extensio...
متن کاملADOPT: Asynchronous Distributed Constraint Optimization with Quality Guarantees ADOPT: Asynchronous Distributed Constraint Optimization with Quality Guarantees
The Distributed Constraint Optimization Problem (DCOP) is able to model a wide variety of distributed reasoning tasks that arise in multiagent systems. Unfortunately, existing methods for DCOP are not able to provide theoretical guarantees on global solution quality while allowing agents to operate asynchronously. We show how this failure can be remedied by allowing agents to make local decisio...

The Distributed Constraint Optimization Problem (DCOP) is a promising approach for modeling distributed reasoning tasks that arise in multiagent systems. Unfortunately, existing methods for DCOP are not able to provide theoretical guarantees on global solution quality while allowing agents to operate asynchronously. We show how this failure can be remedied by allowing agents to make local decis...
متن کاملDFS ordering in Nogood-based Asynchronous Distributed Optimization (ADOPT-ng)
This work proposes an asynchronous algorithm for solving Distributed Constraint Optimization problems (DCOPs) using a generalized kind of nogoods, called valued nogoods. The proposed technique is an extension of the asynchronous distributed optimization (ADOPT) where valued nogoods enable more flexible reasoning, leading to important speed-up. Valued nogoods are an extension of classic nogoods ...
متن کاملHOWTO: Asynchronous PFC-MRDAC -Optimization in Distributed Constraint Problems±Adopt-
Each agent has private problems. Private concerns can often be formulated in a general framework such as constraint satisfaction (where everything is modeled by either variables, values, or constraints). Often agents need to find agreement with others for the allocation of final resources. The constraint satisfaction (CSPs) is only a special case of optimization. Here it is shown how a very gen...
