  • Publication number: 20200142951
    Abstract: A polymer design device according to an embodiment of the present disclosure receives a requirement for a target physical property of a desired polymer, and acquires structural information of polymers. For each polymer corresponding to the acquired structural information, the polymer design device estimates physical property information of the polymer including a mean value and a standard deviation, based on the structural information of the polymer and a regression model, and calculates a score of the polymer based on the requirement for the target physical property and based on the mean value and the standard deviation. From among the acquired structural information of the polymers, the polymer design device selects at least one polymer as the desired polymer, based on the score of each of the polymers, and outputs information of the selected at least one polymer.
