WeightedRandom

A concise C# library for effortless random selection of items from a list, each with its own probability. Perfect for scenarios requiring diverse likelihoods in a simple and efficient package.

Getting Started

Usage

Various examples have been provided in this repo using CLI, WPF, etc.

In a nutshell:

1. Create an array of Option<T>.
   • Each option consists of a Value of type T and an integer representing its Weight.
   • For example: new Option<char>('A', 10) creates an Option for the character A with a weight of 10.
   • Weights are relative to one another. For example, the set of weights [10, 20, 40] is equivalent to [1, 2, 4] or [30, 40, 120], they all give the first entry a 14% change, the second entry a 28% chance, and the third entry a 57% chance.
2. Give that array to a new instance of WeightedRandomizer<T>.
   • You may optionally provide a specific seed value as well. Otherwise the default seed value for System.Random is used
3. Call the method Next() and consume the returned value however you wish.

var options = new []
{
    new Option<char>('A', 10),
    new Option<char>('B', 30),
    new Option<char>('C', 10),
};

var weightedRandom = new WeightedRandomizer<char>(options);

Option<char> selection = weightedRandom.Next();
