Problem A sequence is an ordered collection of objects (usually numbers), which are allowed to repeat. Sequences can be finite or infinite. Two examples are the finite sequence (π,−2–√,0,π)(π,−2,0,π) and the infinite sequence of odd numbers (1,3,5,7,…

Problem Figure 4. A figure illustrating the propagation of Fibonacci's rabbits if they die after three months. Recall the definition of the Fibonacci numbers from “Rabbits and Recurrence Relations”, which followed the recurrence relation Fn=Fn−1+Fn−2…

对数学家来说,Python这门语言有着很多吸引他们的地方.举几个例子:对于tuple.lists以及sets等容器的支持,使用与传统数学类 似的符号标记方式,还有列表推导式这样与数学中集合推导式和集的结构式(set-builder notation)很相似的语法结构. 另外一些很吸引数学爱好者的特性是Python中的iterator(迭代器).generator(生成器)以及相关的itertools包.这 些工具帮助人们能够很轻松的写出处理诸如无穷序列(infinite sequence).随机…

Hi, I'm back. This is a realy classic DP problem to code. 1. You have to be crystal clear about what you are going to solve.2. Apparently there are 2 DP sections3. Think carefully about recurrence relations5. Details: take care of indices boundaries…

Master theorem provides a solution in asymptotic terms to solve time complexity problem of most divide and conquer algorithms. Recurrence relations of the form: T(n) = a T(n/b) + f(n) where a >= 1 and b > 1 Case 1: f(n) = O(nc) where c < logb a T…

In a N x N grid representing a field of cherries, each cell is one of three possible integers. 0 means the cell is empty, so you can pass through; 1 means the cell contains a cherry, that you can pick up and pass through; -1 means the cell contains a…

2018-04-19 19:28:21 股票问题是leetcode里一条非常经典的题目,因为其具有一定的现实意义,所以还是在数学建模方面还是有很多用武之地的.这里会对stock的给出一个比较通用的解法,然后会针对各个细分问题用通解去解决,主要采用的算法是动态规划算法. 问题描述:Given an array representing the price of stock on each day, what determines the maximum profit we can obtain?…
