Interactive reconfiguration in power supply restoration

Given a configuration of parameters that satisfies a set of constraints, and given external changes that change and fix the value of some parameters making the configuration invalid, the problem of interactive reconfiguration is to assist a user to interactively reassign a subset of the parameters to reach a consistent configuration again. In this paper, we present two BDD-based algorithms for solving the problem, one based on a monolithic BDD-representation of the solution space and another using a set of BDDs. We carry out experiments on a set of power supply restoration benchmarks and show that the set-of-BDDs algorithm scales much better.
