[Numpy-discussion] Random number generation and testing across different OS's.
Fri Apr 12 09:50:33 CDT 2013
I have written a differential evolution optimiser that i use for
curvefitting. As a genetic optimisation technique it is stochastic and
relies heavily on random number generators to do the minimisation. As part
of the module tests I would like to write a cross-platform test that checks
if the fitting is being done correctly.
I use an instance of numpy.random.RandomState for the generation. If I use
the seed method on a single platform I get the same output, which I could
use to write a test. However, I am unsure of how the seeding and
RandomState works across platforms.
If I use the same seed on OSX/Windows/Linux, will I get the same stream of
random numbers being generated? I need to know if the test I write works
