ACORN-Js

A JavaScript implementation of ACORN, a k-th order Additive Congruential Random Number (ACORN) generator. More details at http://acorn.wikramaratna.org/concept.html

It's only a nodejs module now. More ToDos below.

Usage

ACORN.prototype.random = function(seed, length)

Generate an array from seed with specified length filled with number in [0,1). To avoid small first element, I recommand to use the seed greater than 10^5.

• seed: Seed for generator. Becareful that using the seed greater than Number.MAX_SAFE_INT will make the seed become zero. BigInt not supported yet.
• length: Length of the returned array.
• Returns an array of generated numbers.

ACORN.prototype.setProperty = function(precision_multiplier, order, auto_correct_seed)

Modify precision, order and option to auto correct seed. For more info about these propertiees please check the link at the begin.

• precision_multiplier: Multipler to multiply the M value, which is 2^30 by default. Default value is 1.
• order: Order. Default is 10000.
• auto_correct_seed: An boolean option to auto correct even seed. Default is true.

ToDo

• A script version for browsers.
• Upload to a CDN for easy include in browsers.
• Make it to npm.
• Unit test for eaier futher development.
  • Monte Carlo value for Pi
  • Arithmetic mean value of data bytes
  • Serial correlation coefficient
• Demo site.
