Project Euler and Dinner
Notice: New feature! Group dinner afterwards for those interested. Maybe/probably Clover in Kendall, around 5pm (or whenever our collective hunger for food outweighs our collective hunger for math). Let's meet up and take a crack at one or more of the awesome math/computer science puzzles ( from the Project Euler ( website! They are not only fun, but you can hone your coding skills, learn some new math, or both! We will start with a problem with a difficulty rating of 25% or less. Possibilities to start with include 609: π sequences (, and 387: Harshad Numbers ( After finishing off an "easy" one, we'll try to wrestle with a more difficult problem, like 473: Phigital number base (, or 300: Protein folding ( If you need a fix of PE excitement before October 28th, new problem 639 is scheduled for release Sunday, October 21st, at 2:00 am (!). Feel free to discuss it over at the forum. . (No solutions please, just preliminary thoughts or raw brute-force output.) Note that everyone is most definitely welcome to arrive after the fun begins, but members who come on time get to vote on what problem we choose to work on! ********************************************* General description of Project Euler meetups... If you are not familiar with Project Euler, it's a site that posts a new problem every two weeks (currently there are over 600). A combination of theoretical math and computer programming are necessary to solve the problem. A brute force algorithm will usually take years to run, but a clever algorithm should return the answer in under a minute on a basic laptop. Generally, the program itself won't be very complex, just CLEVER! Depending on how many people come (and how many laptops), we could split into groups of two or three, and maybe all work on the same problem, or different groups could work on different problems. All are welcome, neither programming skills nor advanced mathematical knowledge is required. Problems almost never rely on knowledge of any math beyond the high school level. **************************************** A NOTE ON THE LOCATION: For first-timers, getting into the building can be a bit tricky. See this page ( for a map and explanation.
