Tentang

VisuAlgo was conceptualised in 2011 by Dr Steven Halim as a tool to help his students better understand data structures and algorithms, by allowing them to learn the basics on their own and at their own pace.

VisuAlgo contains many advanced algorithms that are discussed in Dr Steven Halim's book ('Competitive Programming', co-authored with his brother Dr Felix Halim) and beyond. Today, a few of these advanced algorithms visualization/animation can only be found in VisuAlgo.

Though specifically designed for National University of Singapore (NUS) students taking various data structure and algorithm classes (e.g., CS1010/equivalent, CS2040/equivalent, CS3230, CS3233, and CS4234), as advocators of online learning, we hope that curious minds around the world will find these visualizations useful too.

VisuAlgo is not designed to work well on small touch screens (e.g., smartphones) from the outset due to the need to cater for many complex algorithm visualizations that require lots of pixels and click-and-drag gestures for interaction. The minimum screen resolution for a respectable user experience is 1024x768 and only the landing page is relatively mobile-friendly. However, we are currently experimenting with a mobile (lite) version of VisuAlgo to be ready by April 2022.

VisuAlgo is an ongoing project and more complex visualizations are still being developed.

The most exciting development is the automated question generator and verifier (the online quiz system) that allows students to test their knowledge of basic data structures and algorithms. The questions are randomly generated via some rules and students' answers are instantly and automatically graded upon submission to our grading server. This online quiz system, when it is adopted by more CS instructors worldwide, should technically eliminate manual basic data structure and algorithm questions from typical Computer Science examinations in many Universities. By setting a small (but non-zero) weightage on passing the online quiz, a CS instructor can (significantly) increase his/her students mastery on these basic questions as the students have virtually infinite number of training questions that can be verified instantly before they take the online quiz. The training mode currently contains questions for 12 visualization modules. We will soon add the remaining 12 visualization modules so that every visualization module in VisuAlgo have online quiz component.

We have translated VisuAlgo pages into three main languages: English, Chinese, and Indonesian. Currently, we have also written public notes about VisuAlgo in various languages:

Syarat Guna

VisuAlgo bebas biaya untuk komunitas Ilmu Komputer di dunia. Jika anda menyukai VisuAlgo, satu-satunya "pembayaran" yang kami minta dari anda adalah agar anda menceritakan keberadaan VisuAlgo kepada murid-murid/dosen-dosen Ilmu Komputer yang anda tahu =) lewat postingan Facebook/Twitter/Instagram/TikTok, situs mata kuliah, ulasan di blog, email-email, dsb.


Jika anda adalah seorang murid/dosen struktur data dan algoritma, anda diijinkan untuk menggunakan situs ini secara langsung di kelas-kelas anda. Jika anda mengambil screen shots (video-video) dari situs ini, anda dapat menggunakan screen shots (video-video) tersebut ditempat lain asalkan anda menyebut URL dari situs ini (https://visualgo.net) dan/atau daftar publikasi dibawah ini sebagai referensi. Tetapi, anda TIDAK diijinkan untuk mengunduh berkas-berkas VisuAlgo (sisi-klien) dan memasangnya di situs anda sendiri karena itu dikategorikan sebagai plagiat. Saat ini, kami TIDAK mengijinkan orang lain untuk membuat cabang/varian dari proyek VisuAlgo ini. Menggunakan kopi offline (sisi-klien) dari VisuAlgo untuk kepentingan pribadi diijinkan.


Ingat bahwa komponen kuis online dari VisuAlgo secara natur membutuhkan sisi-server dan tidak ada cara mudah untuk menyimpan skrip-skrip sisi-server dan basis-basis data secara lokal. Saat ini, publik hanya bisa menggunkaan 'mode latihan' untuk mengakses sistem kuis online. Saat ini, 'mode ujian' adalah sistem yang lebih terkontrol untuk menggunakan pertanyaan-pertanyaan yang dibuat secara acak serta verifikasi jawaban otomatis untuk ujian-ujian resmi di NUS.

Kebijakan Privasi

Version 1.1 (Updated Fri, 14 Jan 2022).

Disclosure to all visitors: We currently use Google Analytics to get an overview understanding of our site visitors. We now give option for user to Accept or Reject this tracker.

Since Wed, 22 Dec 2021, only National University of Singapore (NUS) staffs/students and approved CS lecturers outside of NUS who have written a request to Steven can login to VisuAlgo, anyone else in the world will have to use VisuAlgo as an anonymous user that is not really trackable other than what are tracked by Google Analytics.

For NUS students enrolled in modules that uses VisuAlgo: By using a VisuAlgo account (a tuple of NUS official email address, NUS official student name as in the class roster, and a password that is encrypted on the server side — no other personal data is stored), you are giving a consent for your module lecturer to keep track of your e-lecture slides reading and online quiz training progresses that is needed to run the module smoothly. Your VisuAlgo account will also be needed for taking NUS official VisuAlgo Online Quizzes and thus passing your account credentials to another person to do the Online Quiz on your behalf constitutes an academic offense. Your user account will be purged after the conclusion of the module unless you choose to keep your account (OPT-IN). Access to the full VisuAlgo database (with encrypted passwords) is limited to Steven himself.

For other NUS students, you can self-register a VisuAlgo account by yourself (OPT-IN).

For other CS lecturers worldwide who have written to Steven, a VisuAlgo account (your (non-NUS) email address, you can use any display name, and encrypted password) is needed to distinguish your online credential versus the rest of the world. Your account will be tracked similarly as a normal NUS student account above but it will have CS lecturer specific features, namely the ability to see the hidden slides that contain (interesting) answers to the questions presented in the preceding slides before the hidden slides. You can also access Hard setting of the VisuAlgo Online Quizzes. You can freely use the material to enhance your data structures and algorithm classes. Note that there can be other CS lecturer specific features in the future.

For anyone with VisuAlgo account, you can remove your own account by yourself should you wish to no longer be associated with VisuAlgo tool.
