下面是从算法导论(Introduction to Algorithm Edition 3)上copy下的一小段话,解释的相当清楚。 Recurrences go hand in hand with the divide-and-conquer paradigm, because theygive us a natural way to characterize the running times of divide-and-conquer algorithms.A recurrence is an equation or inequalit...
To determine the time complexity of a divide-and-conquer algorithm remains to be a tricky work since some recursions are strikingly intractable. Whereas there is a theorem that can assist us a lot in most cases. The following figure is by courtesy of the renowned algorithm cookbook CLRS: 4....
d$ . Many Divide and Conquer DP problems can also be solved with the Convex Hull trick or vice-versa. It is useful to know and understand both! Practice Problems¶ References¶ Quora Answer by Michael Levin Video Tutorial by "Sothe" the Algorithm Wolf...

A divide and conquer algorithm is a strategy of solving a large problem by breaking the problem it into smaller sub-problems, solving the sub-problems and combining them to get the desired output. In this tutorial, you will understand the working of divi
Quicksort is a classic divide-and-conquer algorithm. It divides a sorting problem into two subsorts. A simple serial version looks like1. void SerialQuicksort( T* begin, T* end ) { if( end-begin>1 ) { using namespace std; T* mid = partition( begin+1, end, bind2nd(less<T>(),...

The goal of Process Mining is to extract process models from logs of a system. Among the possible models to represent a process, Petri nets is an ideal candidate due to its graphical representation, clear semantics and expressive power. The theory of reg
Let us design a divide-and-conquer algorithm to solve this problem. For simplicity of description, assume allnpoints have distinctx-coordinates and distincty-coordinates. Now, we bisectnpoints by a vertical lineL. LetPlbe the set of points lying on the left side ofLandPrthe set of points ...
