Hacking the JavaScript Lottery

January 2016 boasted a Powerball jackpot of 1.5 billion dollars. This generated a lot of interest in the lottery and the Los Angeles Times released a simulator where you start with 100 dollars and play until that is gone. I had seen previous work for predicting Java’s Math.random() and thought it would be a fun project to replicate for the browser. The first step is to find the algorithm used in t

`Math.random()`が利用するXorShift128+のアルゴリズムだと、いくつかの連続した擬似乱数の結果を元に次の擬似乱数の値が予測できるので、乱数としては利用できないという問題。 Z3というsolverで予測をしている
