Abstract: A method for optimizing material properties is provided to reduce test efforts, extend test targets, and remarkably improve optimization speed/precision by applying a dynamic neighborhood concept utilizing an evolution technique to optimization for factors affecting the material properties. A variable group is randomly selected from variables affecting the material properties to be optimized. The properties are evaluated by making materials according to the variable group. A part of the materials is selected among the made materials based on an evaluated property value. The new variable group is obtained from the variables of the selected material by setting a coordinate system using the variables of the material selected among the materials as a reference point and inputting a random number to the coordinate system. The materials are selected by order of excellent property values. Previous steps are repeatedly performed to the obtained new variable group.
