Random number generator

[Mahdi Ben Jelloul]

Dear liam2 users,

I need to be enlightened about the random number generator behaviour.

In my simulation I do have a global parameter that triggers csv files writing.

To mimic "if", I use while in the following way: 

globals:

  - SAVE_SOME_FILES: True

...

trigger: SAVE_SOME_FILES

while trigger:

  - save_my_files()

  - trigger: False 

   

 

In the rest of the code I do some random draws using various distributions, align etc.

To ensure reproducibility, I set a random seed in the main console file. 

But the results differ when the program is run with SAVE_SOME_FILES set to true or false.

Is that the way it should be ?

What are the operations affecting the random number generator ?

Thank you !

Hi Mahdi,

 

Except from the seed command, only functions which generate/uses random numbers affects subsequent random numbers “draws”, so my guess is that you have something using random numbers in your save_my_file() function or any code called from there.

 

Hope it helps,

Gaëtan
