The Freehand Formula Entry System is a research prototype for recognizing online handwritten mathematical notation, developed jointly by researchers in New Zealand, the United States and Canada. A user draws expressions with a mouse or data tablet, and LaTeX, a bitmap, and an operator tree are produced as output. Symbol recognition and expression interpretation are performed as the user draws.
The algorithms package is aimed at being both simple and powerful for typesetting pseudo-code/algorithms in LaTeX documents. Since it uses the (La)TeX engine to generate its output, the results obtained are frequently of high-quality. The package comes with a manual and is quite easy to use in day-to-day documents.
