Hi all, I am the initiator of this project. You can gave me bug reports or suggestions on how to improve VisuAlgo (and its online quiz mode) via [email protected]. Me and my team are still actively developing this tool and will update it over time.
Question banks for certain topics are not big enough so there is a small probability that you can see two random questions that are the same. This should not be true in the near future.
The code is semi open actually (all HTML,CSS,JS files) are on client-side. The only hidden parts (in server-side) are the mechanism to generate random questions and to verify answers automatically and also our graph drawing database :O (you can draw your own graph for DFS/BFS/MST/SSSP/Network Flow/Matching if you haven't notice).
Regarding slow host, it should not be the case in general. Yesterday NUS has network issues that slow down the Internet connection campus wide. Normally it is very fast.
