Ephemeral primitives

[Alessandro Re]

Hello,

I am in the need of creating "random primitives" (random functional), that is, functions that behaves randomly, such as

def add_random(x, y):
     return x + y + some_value

but, some_value, would be something like an ephemeral constant: randomly generated every time the function is used when building a tree.
I thought about using classes with __call__ method defined, but they don't seem to work.

Of course, a kind-of possible solution would be to use STGP and pass some_value with a different type, so that only ephemeral constants of that type could be used, but I am just interested in knowing if is possible to do by creating custom operators, for example using classes or by wrapping functions in some way.

Thanks!

This cannot work as you want it because there is a single implementation of your function and it gets called with various arguments. You would have to use a unic id for each time the function is referenced and store the value for each instance, which looks like a lot of trouble!

Sorry for the delay

Cheers
