Clojure | Rags to Rooks
https://ragstorooks.wordpress.com/2011/07/27/clojure
My thoughts on whatever I am thinking about at the moment, be it work, chess, cricket, or life in general. Laquo; My first ever Gruenfeld. July 27, 2011. I later found (def hello (fn [] “Hello world”) on the clojure website and promptly sent it off to the guys🙂. My “grid” is actually just a vector of 81 elements. Rows, columns and sub-grids are views of the appropriate indices on the vector. Sets up the problem. Uses brute-force in a depth-first manner to solve the puzzle. Learning a new language is alw...

Parallel Sudoku | Rags to Rooks
https://ragstorooks.wordpress.com/2011/08/15/parallel-sudoku
My thoughts on whatever I am thinking about at the moment, be it work, chess, cricket, or life in general. August 15, 2011. Following on from my previous post. Where I wrote a Sudoku solver in Clojure, I tried to improve the performance of the algorithm by having each branch of my search tree execute in a separate thread. I first tried using the ref. I have tried changing around some of the parameters (increasing thread pool size to 1000, decreasing it to 4 – the number of cores on my laptop, incre...

My thoughts on whatever I am thinking about at the moment, be it work, chess, cricket, or life in general. Laquo; Parallel Sudoku. November 2, 2011. Here’s my brute-force clojure solution to Cedric Beust’s latest coding challenge. The code maintains a count of how many weights each combination can measure before iterating through the map and returning the maximum – which of course turns out to be all 40! Candidate) {maxKey maxValue} (if (or (nil? Running it on the clojure console gives me:.

My thoughts on whatever I am thinking about at the moment, be it work, chess, cricket, or life in general. Laquo; Much better, but still losing…. My first ever Gruenfeld. Writing a peer-peer application. February 27, 2011. After spending more than a year writing a p2p application, I thought it was time for me to recap some of our experiences and summarise some of the essentials. Distributed compute and resources. 1 Many small services. Since every invocation of a service could potentially be a request ov...

My first ever Gruenfeld | Rags to Rooks
https://ragstorooks.wordpress.com/2011/03/05/my-first-ever-gruenfeld
My thoughts on whatever I am thinking about at the moment, be it work, chess, cricket, or life in general. Laquo; Writing a peer-peer application. My first ever Gruenfeld. March 5, 2011. I first looked at playing the Gruenfeld about a year ago. Shockingly, since then I hadn’t had anybody playing me as white, play 1. d4 and follow up with 2. c4! Anyway, it was a double-edged sword to play a new opening on the back of two (almost 3) losses. Replay here. 7… c5 is the main line). 20 Qc2 Rfe8 21. Rad1. 41 a4 ...
