Detailed Description

This class implements both the UTIL propagation phase and the VALUE propagation of the ASODPOP algorithm.

It assumes that information on the separator variable domains is discovered online. To mitigate the termination problems that can result from the that, every domain that is not yet full contains a dummy element
