[Algorithm] Write a Depth First Search Algorithm for Graphs in JavaScript

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…

[Algorithm] A* Search Algorithm Basic

A* is a best-first search, meaning that it solves problems by searching amoung all possible paths to the solution(goal) for the one that incurs the smallest cost(least distance, shortest time, etc.), and among these paths it first considers the one t…

[Algorithm] Breadth First JavaScript Search Algorithm for Graphs

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…

笔试算法题（48）：简介 - A*搜索算法（A Star Search Algorithm）

A*搜索算法(A Star Search Algorithm) A*算法主要用于在二维平面上寻找两个点之间的最短路径.在从起始点到目标点的过程中有很多个状态空间,DFS和BFS没有任何启发策略所以穷举所有的状态空间,不适合仅需对局部进行搜索的应用.启发式搜索的关键在于:当前节点在选择下一步节点的时候,可以通过一个启发函数进行选择,选择到达终点代价最小的节点作为下一步节点.A*的启发函数构造为: f(n)=g(n)+h(n) f(n)是可选的下一个节点的代价,g(n)表示从start点到n点…

[Algorithms] Binary Search Algorithm using TypeScript

(binary search trees) which form the basis of modern databases and immutable data structures. Binary search works very much the way humans intuitively search for a name in a yellow pages directory (if you have ever seen one) or the dictionary. In thi…
