This one is in Mathematica, but it's easy to copy to another language, I use it in my games and it can handle decimal weights: (Now I'm talking with a lists first element's index equals 0) The idea behind this is that having a normalized list weights there is a chance of weights[n] to return the index n, so the distances between the min and max at step n should be weights[n]. Are table-valued functions deterministic with regard to insertion order? Each entry should be on a new line or separated by a comma. RAND generates a random value between zero and 1. A Medium publication sharing concepts, ideas and codes. # with a ten-value: ten, jack, queen, or king. Of course you could cache it, but then you're not O(1) for space complexity anymore. Disadvantages: You need to build the array the first time you want to generate an item. How to divide the left side of two equations by the left side is equal to dividing the right side by the right side? In JavaScript: Another strategy is to pick a random number in [0,1) and iterate over the weight specification summing the weights, if the random number is less than the sum then return the associated value. The total distance from the minimum min (which we put it to be 0) and the maximum max is the sum of the list weights. See our full terms of service. I've implemented current algorithm in Ruby https://github.com/fl00r/pickup, The conceptually simplest solution would be to create a list where each element occurs as many times as its weight, so.
