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.
Together with some of his students from the National University of Singapore (see "Team"), a series of visualisations were developed and
consolidated, from simple sorting algorithms to complex graph data structures and algorithms.
Though specifically designed for the use of NUS students taking various data structure and algorithm classes (CS1010,
CS1020, CS2010, CS2020, CS3230, and CS3233), as advocators of online learning, we hope that curious minds around the world
will find these visualisations useful as well.
VisuAlgo is an ongoing project, and more complex visualisations are still being developed.
The most exciting new
development is an automated question generator and verifier (the online quiz system) that allows student to test their
knowledge of basic data structures and algorithms.
The questions are randomly generated via some rules and students'
answers are quickly and automatically graded upon submission to our grading server.

VisuAlgo is not a finished project.
If you spot a bug in any of our visualization page/online assessment tool or if you want to request for new features,
please contact Dr "Steven Halim".
His contact is the concatenation of his name and add gmail dot com.
This work has been presented briefly at the CLI Workshop at the ACM ICPC World Finals 2012 (Poland, Warsaw) and at the
IOI Conference at IOI 2012 (Sirmione-Montichiari, Italy).
This project is made possible by the generous Teaching
Enhancement Grant from NUS Centre for Development of Teaching and
Learning.
