PPT-Distributed Constraint Optimization Problem for Decentraliz

Optimization in MultiAgent Systems At the end of this talk you will be able to Model decision making problems with DCOPs Motivations for using DCOP Modeling practical problems using DCOPs Understand main exact techniques for DCOPs. Optimization methods help us find solutions to problems where we seek to find the best of something.. This lecture is about how we formulate the problem mathematically.. In this lecture we make the assumption that we have choices and that we can attach numerical values to the ‘goodness’ of each alternative.. Approximate Algorithms. Alessandro Farinelli. Approximate Algorithms: outline. No guarantees. DSA-1, MGM-1 (exchange individual assignments). Max-Sum (exchange functions). Off-Line guarantees. K-optimality and extensions. 10.7 – 10.10. Presented by: Shant Karakashian. Symmetries in CP, Sprint 2010. 1. Outline. Successful Applications. Need . for Symmetry Expressions. Manually Providing Symmetries. Easier Symmetry Presentation. Search when states are factored. Until now, we assumed states are black-boxes.. We will now assume that states are made up of “state-variables” and their “values”. Two interesting problem classes.
