MATLAB function to partition very large graphs very fast. This function implements a graph partitioning algorithm based on spectral factorization. This algorithm is described in the following technical report: Joã o Hespanha. An efficient MA

3）必须模拟该4种内存分配算法：first fit，next fit，best fit和worst fit中的至少2种。 4） 需显示出每次分配和回收后的空闲分区链的情况来以及内存占用情况图，并统计各种算法产生的碎片空闲区（小于3个单元（unit）的空闲区）数。 5）计算2个性能参数：碎片数、平均搜索空闲区次数-3) must simulate the four kinds of memory allocation algorithms: first fit, at least two
