Tech History - Evolutionary Algorithms

For the past few thousand years, engineers assumed that the best way to move water round a right angle was as you’d probably expect – just round a bend in the shape of a quarter of a circle. It makes sense; the water pressure is maintained and you’d expect it to flow perfectly round. The engineers did well. They were intuitive, and used the best configuration they knew of. When the first piped water flowed round the fist-ever bend in the first-ever pipe and nothing awful happened, I doubt anyone breathed a sigh of relief. It makes perfect sense it would flow around, and it did, and that’s the way the system stayed until very recently.

The Panda Update: One Year Later

Google Panda was built through an algorithm update that used artificial intelligence in a more sophisticated and scalable way than previously possible. Human quality testers rated thousands of websites based on measures of quality, including design, trustworthiness, speed and whether or not they would return to the website. Google's new Panda machine-learning algorithm, made possible by and named after engineer Navneet Panda, was then used to look for similarities between websites people found to be high quality and low quality.

Many new ranking factors have been introduced to the Google algorithm as a result, while older ranking factors like PageRank have been downgraded in importance. Google Panda is updated from time to time and the algorithm is run by Google on regular basis.
