Sorry to be pedantic, but although Monte Carlo simulations are based on pseudo-randomness, I still think it is good practice that they have deterministic results (i.e., use a given seed) so that the exact results can be replicated. If the precise numbers can be reproduced then a) it helps me as a reviewer see that everything is kosher with their code and b) it means that if I tweak the code to try something out my results will be fully compatible with theirs.
