Dijkstra, A Discipline of Programming introduced with the statement, "is my original idea to publish some beautiful algorithm such that the reader can appreciate their beauty." Dijkstra then provide, as promised, a beautiful collection of algorithms. This algorithm is far ranging, including mathematical calculations, various kinds of problems sorting, pattern matching, convex hull, and much more. However, the value of reading A Discipline of Programming is to absorb and understand how the Dijkstra thinking about this problem, which, in some ways, more valuable than a thousand algorithms.
