Abstract
A method and system for performing a graph search, includes constructing an abstract representation of the graph using state-space abstraction. The abstract representation of the graph includes one or more abstract nodes having duplicate detection scopes and one or more abstract edges having operator groups. The duplicate detection scopes of the abstract nodes are partitioned into smaller duplicate detection scopes using edge partitioning. The abstract edges include the smaller duplicate detection scopes. Nodes in the current search layer are expanded using the operator groups of outgoing abstract edges of the abstract nodes the nodes map to. The operator groups associated with abstract edges having disjoint duplicate detection scopes are used to expand the nodes in parallel. Once all the operator groups in the current search layer have been used for node expansion the method progresses to the next search layer.
