I was looking for this algorithm
(algorithm which will randomly select from a list of elements where each element has different probability of being picked (weight) )
and found only python and c implementations, after I did a C# one, a bit different (but I think simpler) I thought I should share it, and ask your opinion ?
this is it:
using System;
using System.Collections.Generic;
using System.Linq;
namespace ChuckNorris
{
class Program
{
static void Main(string[] args)
{
var oo = new Dictionary<string, int>
{
{"A",7},
{"B",1},
{"C",9},
{"D",8},
{"E",11},
};
var rnd = new Random();
var pick = rnd.Next(oo.Values.Sum());
var sum = 0;
var res = "";
foreach (var o in oo)
{
sum += o.Value;
if(sum >= pick)
{
res = o.Key;
break;
}
}
Console.WriteLine("result is "+ res);
}
}
}
if anyone can remake it in f# please post your code
