In this paper we study the problem of distributed construction of a depth-first-search tree for an asynchronous communication network. First, we point out that any algorithm requires at least 2n2 time units and
Depth First Search is a recursive algorithm for searching all the vertices of a graph or tree data structure. In this tutorial, you will learn about the depth-first search with examples in Java, C, Python, and C++.

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');functioncreateNode(key) { let children=[];re...

Depth first search algorithmWith the amount of available text data on the web growing rapidly, the need for users to search such information is dramatically increasing. Full text search engines and relational databases each have unique strengths as development tools but also have overlapping ...
In this paper, we propose an external memory depth first search algorithm for general grid graphs. The I/O-complexity of the algorithm is O(sort(N)log2NM), where N=|V|+|E|, sort(N)=Θ(NBlogM/BNB) is the sorting I/O-complexity, M is the memory size, and B is the block size...
Standard breadth-first search (BFS) is an algorithm for finding nodes from a starting node or nodes in a graph in breadth-first order. It returns the source node or nodes that it started from, and all of the nodes visited by each search. Note Because every source node passed in leads ...

A Heuristic Search Algorithm, such as the A* algorithm, is defined as a best-first search method that uses a combination of cost functions and heuristic functions to find the optimal solution in a state space by expanding nodes with the lowest estimated cost. ...
