How to generate distinct random numbers per distinct threads in .NET?


How to generate distinct random numbers per distinct threads in .NET?

wish of those help Well how many threads are you actually going to use? That's the limiting factor. If you only need (say) 8 threads then you can just lose 3 bits of information. You could create a "generator factory" which knows how many generators it's allowed to create, and throws an exception if you try to create too many.
Your requirement for distinct numbers isn't very clear though - even if you make sure that one thread never creates the same number that another thread has created, you still have to worry about whether you create a duplicate number on the same thread. Is that a problem for you or not?

I hope this helps you . quick question: , Here is my attempt using splice:
code :
var a = [1,2,3,4,5,6,7,8,9,10];var sample = [];
sample.push(a.splice(Math.random()*a.length,1));
sample.push(a.splice(Math.random()*a.length,1));
function sample_range(range, n) {
  var sample = [];
  for(var i=0; i<n; i++) {
    sample.push(range.splice(Math.random()*range.length,1));
  }

  return sample;
}

var sample = sample_range([1,2,3,4,5,6,7,8,9,10], 2);
Array.prototype.sample_range = function(n) {
    var sample = [];
    for(var i=0;i<n;i++) {
      sample.push(this.splice(Math.random()*this.length,1));
    }
    return sample;
};
var sample = [1,2,3,4,5,6,7,8,9,10].sample_range(2);

this will help I'm using smarty v2.6 and I want to generate random distinct numbers. I'm looking for an efficient, fast way to do it using already provided Smarty functions. This is my code for generating 5 random numbers (but not distinct): , if you really need to do it in smarty templates
method 1
code :
{assign var="distinct_numbers" value=array_fill(1,15,'x')}
{assign var="distinct_numbers" value=array_keys($distinct_numbers)}
{assign var="x" value=shuffle($distinct_numbers)}

{* result *}

{foreach from=$distinct_numbers item="value"}
    {$value} |
{/foreach}

wish help you to fix your issue The answer is not always because the result of your query will be only the distinct values of your random numbers so if you generate the same random number 2 times, that number will appear only 1 time (you will lose 1 record).

Any of those help you could use random.choice:
code :
import numpy as np

np.random.choice(a=np.arange(4), size=2, replace=False)
np.random.choice(a=4, size=2, replace=False)
