USC Distributed Constraint Optimization Problem (DCOP) Repository

In a DCOP, cooperative agents, each in control of one or more variables, work together to optimize a set of constraints that exist upon the variables.  This page contains DCOP datasets and variations of the ADOPT and incomplete algorithms for solving DCOP.  ADOPT is a polynomial space algorithm that is guaranteed to find an optimal solution, or a solution within a user-specified distance from the optimal, while allowing agents to execute asynchronously and in parallel.
