I created 5 AVL Pages:
These are all part of a larger system called Calculus. Calculus has many more classes. Calculus was first created in 2006 in C# (although the algorithms date back to 1987).
More recently Applied Calculus was created. Pure Calculus resides in memory whereas Applied Calculus is on disk. The on-disk algorithms are much harder to master.
