本文提出了一种从N(M≤N)个样本中抽取M个随机样本的算法。该算法的时间复杂度为MIN {O(Mlog 2 M),O[(N-M)log 2(N-M)]},空间复杂度为O(M)。
An algorithm for drawing a random sample of size M from the population of size N (M≤N) has been proposed. The algorithm has the time complexity of MIN {O(Mlog2M), O[(N−M)log2(N−M)]} and the space complexity of O(M).
