http://www.algoblog.com Algorithms are the language of nature. Tue, 31 Jul 2007 03:02:05 +0000 http://backend.userland.com/rss092 en Hey everyone, Thanks for still keeping tabs on me. I'll post something tomorrow morning. Stay tuned! http://www.algoblog.com/2007/07/30/stay-tuned/ Suppose you are a real estate developer. These days, the market is getting tight so you have decided to turn to algorithms to give you an edge over the competition. You have purchased an irregularly shaped plot of land which you have divided into a square grid. ... http://www.algoblog.com/2007/06/13/real-estate-optimization/ A question often asked in interviews is: what's the best way to store a set? There are many different ways to store well-ordered data so that it can be queried quickly. Many people find that a hash table gives them the best performance characteristics, so much so that ... http://www.algoblog.com/2007/06/08/finding-an-enclosing-interval/ I've made a few tweaks to the blog. There are a few minor cosmetic changes. Also, comments are now protected using WP HashCash. Contact me via email if you have trouble. I'm preparing a new algorithm post which should be ready within 12 hours. Stay tuned! http://www.algoblog.com/2007/06/07/a-few-tweaks/ So, I've totally been writing this blog for almost a week, but so far I haven't talked about how an actual algorithm works. Here's a classic algorithm. Let's say you have an array of n elements a[0] through a[n-1]. You would like to generate a random permutation of this ... http://www.algoblog.com/2007/06/04/permutation/ We all use algorithms every day, but what is an algorithm, exactly? By my definition, an algorithm is a formalized procedure to accomplish a task (this is essentially the same as Wikipedia's). Not everything you do is an algorithm. Some things we do have no known good algorithm, such ... http://www.algoblog.com/2007/05/30/what-is-an-algorithm/ Ask.com has recently launched an ad campaign centered around "the algorithm". They are obliquely referring to their search algorithm "Teoma" when they say "The algorithm is from Jersey". They even ran a full-page ad in various major newspapers written in the style of an academic article. The ad ... http://www.algoblog.com/2007/05/29/asks-algorithm/ Howdy. This is my blog about algorithms. Posts will fall into the following categories: Algorithms assigned as homework problems. These will be tagged as 'edu'. I welcome submissions via email. I will always follow these guidelines: I will only post about problems accessible from the "general web", by which ... http://www.algoblog.com/2007/05/29/introduction/
