Detailed Description

Parallel search.

A parallel search finds which domain entities satisfying the domain predicate are correctly mapped to the range entities satisfying the range predicate. The result of the search is a graph mapping the domain to the range and the parametric coordinates of the range entity centroids in their respective domain entities.

The search has two simultaneous states: one in the parallel decomposition of the domain and one in the parallel decomposition of the range. The interface functions assume one decomposition or the other.
