Changing seed number - be careful #1005

Open AdimDrewnik opened 1 week ago

AdimDrewnik commented 1 week ago

When running Robyn with different seeds be careful when changing the seed value. For example if you run seed = 123 with 10 trials and later run seed 124 with 10 trials then 9 out of 10 trials will have the same seed in the both runs. Seed number must be changed by more than the number of trials if someone wants completely new RNG in the whole run.
