相比于遍历所有的位数进行判断,Brian Kernighan's Algorithm的优势在于,它只需要执行与1的个数相等的循环次数,即执行次数等于二进制表示中1的个数。这使得该算法在时间复杂度上更加高效。 这个算法以Brian Kernighan的名字命名,因为他在1988年的《The C Programming Language》一书中介绍了这种方法,用于计算一个整数的...

If you have ever worked on placement or floorplanning, and probably some other areas of EDA, then you will have heard of "Kernighan and Lin". It's a partitioning algorithm. You might not even have realized that the Kernighan of Kernighan and Lin is the same person as the Kernighan of K...
