  • Method of utilizing product proxies with a dependency graph
    Patent number: 7945892
    Abstract: Changes to the outputs of a dependency graph, which has attribute nodes and operator nodes, are detected by forming product proxies for the outputs of dependency graph nodes. The product proxies can be formed by entering information about the dependency graph into a hashing algorithm. Before and after product proxies are then used to determine if the outputs have changed.
