Additionally, we have authored public notes about VisuAlgo in various languages, including Indonesian, Korean, Vietnamese, and Thai: id, VisuAlgo has been translated into three primary languages: English, Chinese, and Indonesian. Each VisuAlgo visualization module now includes its own online quiz component. By assigning a small (but non-zero) weight to passing the online quiz, CS instructors can significantly enhance their students' mastery of these basic concepts, as they have access to an almost unlimited number of practice questions that can be instantly verified before taking the online quiz.

As more CS instructors adopt this online quiz system worldwide, it could effectively eliminate manual basic data structure and algorithm questions from standard Computer Science exams in many universities. Questions are randomly generated based on specific rules, and students' answers are automatically graded upon submission to our grading server.

At present, the platform features 24 visualization modules.Įquipped with a built-in question generator and answer verifier, VisuAlgo's "online quiz system" enables students to test their knowledge of basic data structures and algorithms. VisuAlgo remains a work in progress, with the ongoing development of more complex visualizations. However, since April 2022, a mobile (lite) version of VisuAlgo has been made available, making it possible to use a subset of VisuAlgo features on smartphone screens. For an optimal user experience, a minimum screen resolution of 1366x768 is recommended. Initially, VisuAlgo was not designed for small touch screens like smartphones, as intricate algorithm visualizations required substantial pixel space and click-and-drag interactions. While primarily designed for National University of Singapore (NUS) students enrolled in various data structure and algorithm courses (e.g., CS1010/equivalent, CS2040/equivalent (including IT5003), CS3230, CS3233, and CS4234), VisuAlgo also serves as a valuable resource for inquisitive minds worldwide, promoting online learning.
Suhendry Effendy - VisuAlgo remains the exclusive platform for visualizing and animating several of these complex algorithms even after a decade. Steven Halim's book, 'Competitive Programming' - co-authored with Dr. Steven Halim, VisuAlgo aimed to facilitate a deeper understanding of data structures and algorithms for his students by providing a self-paced, interactive learning platform.įeaturing numerous advanced algorithms discussed in Dr. Since a graph may contain cycles, a visited hash set is used to keep track of all visited nodes.Initially conceived in 2011 by Dr.
A start node is added to the queue to start.Īs long as the queue is not empty, a node is removed and its unvisited neighbors are added to the queue. Import import import import import class Main īreadth First Search uses a queue to traverse the graph in a level like manner. It contains a value and an array list of neighboring nodes. Node objectįirst, we will create a Node object.

These values can be positive or negative.Īll the code can be found here: press the Run button at the top to run. Unweighted graphs have zero value edges, while weighted graphs have non-zero value edges. Directed graphs can only be traversed in the direction the edges point. Undirected graphs have directionless edges between nodes.ĭirected graphs have edges that point in a direction. All graphs have nodes and edges, but there are different structures and properties between different types. There are different types of graphs, like undirected, directed, weighted, unweighted, etc.
