Abstract:

An apparatus and method for determining a solution to a problem where paths in at least one pursuit associated with the problem are traversed to generate one or more decision paths by processing one or more nodes in a given one of the paths, including: evaluating a premise if the node is a premise node, and passing the premise node if the premise passes, and noting a conclusion if the node is a conclusion node, withdrawing any previous conclusions that are not associated with a parent node of the conclusion, and passing the conclusion node; processing a child node if the current node is not a leaf node and is a node that passes; terminating a decision path if the child node cannot be processed, including asserting all noted, but non-withdrawn conclusions as a solution to the problem; and generating another decision path.
