Models and simulations course. Pseudo random number generation programs
System requirements:
- nodeJS. LTS is preferred
- npm. 6 - 7
Before running any funtion, you must run npm install or npm i
This repo contains three functions to generate pseudo random numbers:
This function iterates taking the k central central number from the iteration's squeares, it can be ran by executing:
$ node cuadrados_centrales.js| Param | Importance | Type of value | Description |
|---|---|---|---|
| seed | s | Mandatory | number | The seed value passed to the program, this will be used to create the first iteration |
| k | Mandatory | number | The number of numbers that will be taken from each iteration. Seed must be lower than 10^k |
| stopWhenRepeated | Optional | 1 | 0 | This will set the variable that will stop the iterations when a result loop is found. Default 1. |
| maxIterations | Optional | number | This will set the maximum iterations to the program. Default 100 |
$ node cuadrados_centrales.js --seed 304 -k 3 --stopWhenRepeated 0 --maxIterations 150
$ node cuadrados_centrales.js -s 501 -k 3This function iterates taking k central numbers from the iteration's product, it can be ran by executing:
$ node productos_centrales.js| Param | Importance | Type of value | Description |
|---|---|---|---|
| seed1 | Mandatory | number | The frist seed value passed to the program, this will be used to create the first iteration |
| seed2 | Mandatory | number | The second seed value passed to the program, this will be used to create the first iteration |
| k | Mandatory | number | The number of numbers that will be taken from each iteration. Seed must be lower than 10^k |
| stopWhenRepeated | Optional | 1 | 0 | This will set the variable that will stop the iterations when a result loop is found. Default 1. |
| maxIterations | Optional | number | This will set the maximum iterations to the program. Default 50 |
$ node productos_centrales.js --seed1 304 --seed2 512 -k 3 --stopWhenRepeated 0 --maxIterations 150
$ node productos_centrales.js --seed1 501 --seed2 273 -k 3This function iterates using the mix congruential method, it can be ran by executing:
$ node congruencial_mixto.js| Param | Importance | Type of value | Description |
|---|---|---|---|
| seed | Mandatory | number | The seed value passed to the program, this will be used to create the first iteration |
| a | Mandatory | number | The multiplicative constant for the iteration |
| c | Mandatory | number | The additive constant for the iteration |
| m | Mandatory | number | The number to take the module from |
| stopWhenRepeated | Optional | 1 | 0 | This will set the variable that will stop the iterations when a result loop is found. Default 1. |
| maxIterations | Optional | number | This will set the maximum iterations to the program. Default 100 |
$ node congruencial_mixto.js --seed 73 -a 65 -c 14 -m 92 --stopWhenRepeated 0 --maxIterations 150
