Shuffle / Random nodes based on what formula or principle?

Hello, I am wondering the nodes - 1. List.Shuffle; 2. Math.Random. What kind of rule or formula they apply to generate random stuffs?

you can see the source for the random and math classes here:

github.com

DynamoDS/Dynamo/blob/d424b31ae0bccaf99de09b003850a87db0eb60d1/src/Libraries/CoreNodes/Math.cs#L48


    return result;
}


/// <summary>
///     Produces a list containing the given amount of random doubles
///     in the range of [0, 1).
/// </summary>
/// <param name="amount">Amount of random numbers the result list will contain.</param>
/// <returns name="number">List of random numbers between 0 and 1.</returns>
/// <search>random,listcontains</search>
public static IList RandomList(int amount)
{
    var result = new ArrayList();


    foreach (var x in Enumerable.Range(0, amount).Select(_ => mRandom.NextDouble()))
        result.Add(x);


    return result;
}


/// <summary>

this should all be using the .net random classes in most places so see MSDN: https://msdn.microsoft.com/en-us/library/system.random(v=vs.110).aspx

Michael,

Thank you so much.

I also want to know the difference between Shuffle and Random. Any idea? Thanks.
