Reaction path search for storage media reaction path search method, reaction pathways and retrieval device

摘要

PROBLEM TO BE SOLVED: To make it possible to search for the shortest avoiding route at a high speed while avoiding an obstacle place such as a compd. or reaction to be an obstacle. SOLUTION: The shortest avoiding route being a reaction route from a starting compd. to a final compd. and not passing an obstacle place of a compd. or reaction to be an obstacle is searched by using reaction route data consisting of compd. data and reaction direction data between compds. An input step receiving the input of the data related to the starting compd. and the final compd. and the data related to the obstacle place, a reading step reading reaction route data from a memory means 20 on the basis of the data of the starting compd. and final compd. received in the input step, an extraction step extracting the shortest avoiding route from the starting compd. to the final compd. on the basis of the data of the obstacle place received in the input step and the reaction route data read in the reading step and an output step outputting the avoiding route extracted in the extraction step are provided.
