重新定义权为:剖分弦的长度和加上多边形的周长(显然等价),重新求解

本函数还适用于任何定义在剖分后的三角形上的权的情况(修改一下)

例如权为三角形的面积的面积平方和-To redefine the right as follows: Partition string plus the length and circumference of polygons (apparently equivalent), re-solving this function also applies to any definition of the triangle at the post-partition on the right (changed a bit) such as the right to the size of the area of the triangle and square
