発明の名称 (英語) FINITE FLOW PATTERN WORD REPRESENTATION DEVICE, WORD REPRESENTATION METHOD, AND PROGRAM, STRUCTURE SHAPE LEARNING METHOD, AND STRUCTURE DESIGNING METHOD 新技術説明会
発明の概要(英語) This word representation device is provided with a storage unit and a word representation generating unit, wherein: the storage unit stores, in relation to a plurality of streamline structures forming a flow pattern, a correspondence relationship between each streamline structure and a letter relating thereto; the word representation generating unit is provided with a root determining means, a tree representation forming means, and a COT representation generating means; the root determining means determines the root of a given flow pattern; the tree representation forming means repeatedly executes processing, sequentially from the innermost portion of a given flow pattern until the root is reached, to extract the streamline structure of the given flow pattern, assign a letter to the extracted streamline structure on the basis of the correspondence relationship stored in the storage unit, and delete the extracted streamline structure, thereby forming a tree representation of the given flow pattern; and the COT representation generating means generates a word representation of the given flow pattern by converting the tree representation formed by the tree representation forming means into a COT representation. Further, a trained AI is caused to calculate the structure shape that causes a desired flow pattern to form at the periphery thereof.
従来技術、競合技術の概要(英語) BACKGROUND ART
A technique for providing a many-to-one word expression (maximum word expression) to a flow pattern of an incompressible fluid on a curved surface and a method for designing a shape of a structure in a fluid using the word expression and the regular expression are disclosed (see Patent Document 1, for example). In addition, a technique for acquiring transition information relating to a transition route from a structurally stable streamline pattern in a topological two-dimensional flow structure to another structurally stable streamline pattern that can be taken topologically is disclosed (see, for example, Patent Document 2). Furthermore, technology has been disclosed in which word expressions (regular expressions) are given to the flow structure of the incompressible fluid on the curved surface from graphical expressions corresponding to the flow pattern on a one-to-one basis, and technology that optimizes the shape of the structure in the fluid using the word expressions (see Patent Document 3, for example).
