Abstract
A system and method for determining variable orders for decision diagrams. The variable orders are determined by sampling subspaces of a Boolean space representing a function or circuit. The subspaces are formed in a variety of ways, including through the use of abstraction, decomposition, partial assignments, and circuit subspaces.
