13. A computer system that identifies policy conflicts between a base policy and a changed policy, comprising: a first specialized computer system formed by configuring the computer system using a first segment of a software program, the first specialized computer system generating a first graph that represents the base policy, the first graph including a plurality of base nodes and one or more base edges, each of the base nodes having a content and an identity, the content of each of the base nodes representing an attribute, a logic statement and/or a decision statement of the base policy, and the base edges representing one or more semantic relationships among the base nodes; a second specialized computer system formed by configuring the computer system using a second segment of the software program, the second computer system generating the identity of each base node by hashing the content of the base node and an identity of each child-base node of the base node; a third specialized computer system formed by configuring the computer system using a third segment of the software program, the third specialized computer system generating a second graph that represents the changed policy, the second graph including a plurality of changed nodes and one or more changed edges, each of the changed nodes having a content and an identity, the content of each of the changed nodes representing an attribute, a logic statement and/or a decision statement of the changed policy, and the changed edges representing one or more semantic relationships among the changed nodes; a fourth specialized computer system formed by configuring the computer system using a fourth segment of the software program, the fourth specialized computer system generating the identity of each changed node by hashing the content of the changed node and an identity of each child-changed node of the changed node; a fifth specialized computer system formed by configuring the computer system using a fifth segment of the software program, the fifth specialized computer system comparing base decision paths against changed decision paths, each of the base decision paths extending from a base root-node to a base node whose content represents a base decision, each of the changed decision paths extending from a changed root-node to a changed node whose content represents a changed decision; and a sixth specialized computer system formed by configuring the computer system using a sixth segment of the software program, the sixth specialized computer system outputting a base decision path that does not have a corresponding changed decision path, and a changed decision path that does not have a corresponding base decision path as potentially conflicting paths.
