通过逐一考查全体特征值，实现图同构的判定并确定同构图的顶点对应关系。
After all the eigenvalues have been considered, isomorphism will be determined and correspondence of vertices in isomorphic graphs can be ultimately identified.
根据两多边形的形心—顶点连线长度及相邻连线之间的夹角给出匹配度函数，并以此来建立两多边形顶点之间的对应。
According to the lines of centroid and vertex, and angles between the two adjacent lines, a function is given and then a correspondence is established between the two polygons.
顶点所对应的可行解称为基本可行解。
