Conformity as Necessary

I wonder whether to repeat we shouldn't have something that allows us to do it? A computer which works on modelling some patterns must have the set of functions and an algorithm for such a procedure. As soon as in ya claim all the phenomena repeat itself, then each phenomena (or anything behind them) must have all the functions and the algorithms for being able to repeat itself. Just note: if I would like to copy myself I gotta have an image of myself firstly. Without it there's no repeating. And I gotta know all the functions and algorithms to be able to repeat, because I might've been changed, and I gotta be prepared for this operation. And I think such a plan is too complex. Maybe, the things are like that. I don't know, while it sounds to difficult to perform it or any phenomenon or an element of the Being is similar to Leibniz's monads.
