分治法的基本思想是将问题分成(divide)多个子问题,再递归(Conquer)的解决每个子问题,再将子问题的解合并(Combine)成原问题的解。 1)这个思想是不是很熟悉,第一反应能不能想到归并排序和快速排序。后面我们会对两种排序和分治法的思想进行具体分析。 2)分成多个子问题,有没有想到动态规划和贪心法,它们有什么区别呢...

对归并排序而言,设将长度为n的序列排序所需时间为T(n),那么就存在递归关系:T(n) = 2T(n / 2) + O(n),进而推导出渐近时间复杂度为:O(n logn)。对于基于分治法的算法,其时间复杂度都可以通过分治法主定理(Master theorem for divide-and-conquer recurrences)来推导。关于该定理,详细的说明可以参见英文维...
