A - Breadth-First Search by Foxpower Problem Statement Fox Ciel went to JAG Kingdom by bicycle, but she forgot a place where she parked her bicycle. So she needs to search it from a bicycle-parking area before returning home. The parking area is form…
Breadth first search is a graph search algorithm that starts at one node and visits neighboring nodes as widely as possible before going further down any other path. This algorithm requires the use of a queue to keep track of which nodes to visit, so…
Depth first search is a graph search algorithm that starts at one node and uses recursion to travel as deeply down a path of neighboring nodes as possible, before coming back up and trying other paths. const {createQueue} = require('./queue'); func…

绘制了一张导图,有不对的地方欢迎指正: 下载地址 机器学习中,特征是很关键的.其中包括,特征的提取和特征的选择.他们是降维的两种方法,但又有所不同: 特征抽取(Feature Extraction):Creatting a subset of new features by combinations of the exsiting features.也就是说,特征抽取后的新特征是原来特征的一个映射. 特征选择(Feature Selection):choosing a subset of all…
自从工作后就没什么时间更新博客了,最近抽空学了点Python,觉得Python真的是很强大呀.想来在大学中没有学好数据结构和算法,自己的意志力一直不够坚定,这次想好好看一本书,认真把基本的数据结构和算法补一补. Python讲数据结构和算法的书,我想说的是真的太少了!!广泛搜索,中文的图书基本上没有,倒是找到两本外文的: Problem Solving with Algorithms and Data Structures (用Python讲解数据结构与算法) Python Algorithms…

Check whether a given graph is Bipartite or not A Bipartite Graph is a graph whose vertices can be divided into two independent sets, U and V such that every edge (u, v) either connects a vertex from U to V or a vertex from V to U. In other words, fo…
Given a Directed Graph and two vertices in it, check whether there is a path from the first given vertex to second. For example, in the following graph, there is a path from vertex 1 to 3. As another example, there is no path from 3 to 0. We can eith…
