算法-分治法(Divide-and-Conquer) 分治法简介 分治法是把一个复杂的问题分成两个或多个相同或相似的子问题,再把子问题分成更小的子问题直到最后子问题可以简单地直接求解,原问题的解即子问题的解的合并,这个思想是很多高效算法的基础。 分治法的基本思想:将一个难以直接解决的大问题,分割成一些规模较小的相同问题...
A recurrence of the form in equation (4.2) characterizes a divideand-conquer algorithm that creates a subproblems, each of which is 1=b the size of the original problem, and in which the divide and combine steps together take f(n) time. ...
