Re: [Swarm-Support] Query regarding changing seed in a RNG

[Diego Corredor]

Hi Steve,

I would like to know if there is a way to change the seed used by the
ListShuffler. I would like to be sure that the results observed in the
model that I have programmed are robust to the order of interaction
among consumers and firms.

Thanks,

Diego Corredor
