I'd encourage you to spend many luxurious afternoons…browsing the code and admiring the wisdom…of these many programmers who have spent countless hours…solving the N queens problem.…
Mark introduces challenges and then provides an overview of his solutions in R. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
