Indeed we believe that deep understanding of a small number of algorithms in this manner provides a stronger base for further study of computer graphics than does a superficial understanding of many.

The advantages mathematicians have when it comes to programming are experience with ways to precisely describe algorithms and logic and experience reasoning from first principles. The retrospective is fascinating to get an idea of just how Knuth approaches software construction. Besides demonstrating the techniques of clear, efficient coding, Knuth has sought to bring a deeper sense of aesthetics to the discipline. Books by Donald Ervin Knuth. Anywhere else, traceability is mostly wishful thinking shared by the many owners of physically disconnected documents.

These arbitrary explanatory phrases become precise new operators, created on the fly by the programmer, forming a meta-language on top of the underlying programming language. Then, to understand the complicated literste, what you needed is just to understand the small parts, and to understand the relationship between those parts and their neighbors. Ships from and sold by Amazon. Actually, writing out the expanded source code can be done from any section or subsection i. The main intention behind this approach was to treat a program as literature understandable to human beings.

Innovative ideas, critical technical knowledge, algorithmic solutions, and unusual coding constructions are clearly documented. If literate programming ever takes off, it won't look quite like this. The articles have been revised, extended, and brought up to date. All in all, it's a good book, especially for those who find almost everything written by Knuth deeply enjoyable.

But sigh it probably isn't. Knuth is professor emeritus of the art of computer science at Stanford University. Rather, the point is that this style can more easily motivate others including your future self to read an implementation, such that they can more easily find the bugs. Drawing and Literate Programming. There are many examples in this book of what Knuth did aside from Literate Programming.

Such exposition of ideas creates the flow of thought that is like a literary work. Instead, it is wrenched into the daylight and made the main focus. This approach was implemented at Stanford University as a part of research on algorithms and digital typography. Literate programs are written to be read by other software developers.

These macros are similar to the algorithms in pseudocode typically used in teaching computer science. In summary this book is a good read to see how one smart guy a while ago in computer terms tried to improve his code writing ability. This volume is first in a series of Knuth's collected works.
