Aside from his professional pursuits, George is an avid puzzler. He invented Sujiken®, a Sudoku variation played on a right-triangle arrangement of cells in which numbers cannot repeat in a horizontal row, vertical column or diagonal in any direction. See more at http://www.sujiken.com.

May Column: Multi-threaded Algorithm Implementations
June 19 2009
Many of the algorithms presented in the book can take advantage of multi-core chips by using threads. In this column we explore effective uses of threads and report on situations where using threads will not help. read moreApril Column: Computational Geometry
May 15 2009
Computational Geometry is the study of geometric algorithms and the data structures that enable their efficient implementation. We present algorithms that solve the Line Segment Intersection problem and describe challenges in validating their implementation read moreMarch Column: Network Flow Algorithms
April 06 2009
Many real-world transportation networks (i.e., highways, power grids, water subsystems) can be represented as Flow Networks. The Ford-Fulkerson technique describes an approach to solve numerous cost optimization problems. read moreFebruary Column: Improving Performance Of Algorithms
March 03 2009
You need two different techniques for optimizing the performance of an algorithm. Sometimes you improve upon the algorithm; sometimes you improve the way the algorithm is implemented. Both techniques are essential to applying algorithms properly. read moreJanuary Column: Algorithm to Solve FreeCell Solitaire Games
January 18 2009
We describe how to use recursive backtracking to solve a search problem. We design a staged deepening algorithm to solve FreeCell solitaire games. This material is not drawn from the book, but rather helps to place the graph searching algorithms in a better context. read moreDecember Column: Searching Algorithms
December 04 2008
In the second monthly column for the blog associated with the Algorithms in a Nutshell, we investigate searching algorithms and reaffirm the ability for hash-based search to provide an efficient implementation. read moreNovember Column: Welcome to Algorithms in a Nutshell
October 25 2008
This is the first of a series of monthly columns in the blog associated with the Algorithms in a Nutshell, published October 2008 by O'Reilly Media, Inc. All algorithms are fully implemented and available in the online code repository associated with the book. read moreRecent Posts | All O'Reilly Posts
