Recursion is something that many computer science majors consider elegant. However, in simulation, speed far outweighs how many lines of code are underneath. [That is one reason why physicists still code in Fortran.]

How do we assign priors?
If we don’t have any prior knowledge, then the obvious solution is to use the principle of indifference. This principle says that if we have no reason for suspecting one outcome over any other, than all outcomes must be considered equally likely. Jakob Bernoulli called this the “principle of insufficient reason”, a play on the “principle of sufficient reason”, which asserts that everything must have a reason or cause. This may be the case, but if we are ignorant of reasons, we cannot say that one outcome will be more likely than any other.
