IPC: G06F9/06
Filed: 1990-11-19
Abstract: PURPOSE:To optimize state transition information by providing a sequential simplification device, a state transition storage device, and a backward simplification device, and automatically retrieving and deleting a redundant part possibly included in the state transition information. CONSTITUTION:The sequential simplification device 2 retrieves the transition origin arc list of a start node in the state transition storage device 1 first to search for a pair of arcs which have the same attribute and the same transition destination node attribute. When the pair of arcs are found, a sequential deletion routine is called and then the control is returned. In the case of a failure in the retrieval, a sequential simplification routine is called by using the node identifier of a node, which is not simplified yet among nodes capable of moving from the start node, as an argument. After returning, the node is given a mark indicating that the simplification is done. Thus, the redundant part which is possibly included in the state transition information is automatically retrieved and deleted.
