Subalgorithm[edit | edit source]

Algorithms are often broken down into smaller chunks, called Subalgorithm. This is both so that they are easier to read, and also because then parts of the algorithm can be reused. What follows is the above algorithm in a more formal manner. The text in italics below are the names of the Subalgorithm that are being called.
