A free collection of 112 (one hundred twelve) Mathematica algorithms
Version:The textbook by Crandall and Pomerance has this exact number---112---of pseudocode displays.
Operating System: Mac OS X
The 112 programs in Mathematica were created by various authors: student interns, professors, programming experts (not to imply these affiliations have no intersection!).
Some of them were given advance drafts of the textbook and challenged in regard to implementation of the (sometimes tough) algorithms.
The Mathematica renditions herein therefore have a non-uniform flavor, sometimes for good reason; experts, as we all are aware, differ in style, intent, design, etc.
