Join Mark Niemann-Ross for an in-depth discussion in this video Further information about eight queens, part of Code Clinic: R (2015).
- The eight queens is a fascinating problem,…and oftentimes you'll hear it referred to…as the N queens problem,…because you can go on with more than just eight queens.…Of course, the more queens you put in,…the longer it takes to solve.…Fortunately, there have been solutions…written in many different languages,…and if you go to RosettaCode.org,…you'll see a listing of many, many,…many different languages that have been used…to solve the eight queens problem,…including the actual source code…for each of those solutions.…
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.
