Hi all,

I have been looking for posts about random values following specific distribution and find options of using Java or code the pdf mathematically.  

I would like to try both. But I dont have any basics of Java and pdf of gamma is a integration of the exponential function. 

I wonder do we have any model examples about how to setup the random numbers following specific distribution?

Thanks,
Jia

Hi,

you could call some java from OPL as can be seen in OPL scripting

You could also call python:

import numpy as np

f = np.random.gamma(3, 20, 10)
print(f)​

to generate values that you would then use within OPL
