How do you optimize a system while preserving an unknown function? (Optimization, Machine Learning, Evolutionary Computation, Control Theory, etc.)

I'm trying to abstract a biological problem into a more general computational problem, as I'm interested in the underlying methodology used in this fields, to ideally translate back to biology.

The core challenge is that I want to modify a system while preserving a desired behaviour in one context, but allowing that behaviour to change in other contexts. The difficulty is that I don't know which internal parts of the system are responsible for preserving the desired behaviour.

A simplified example:

  • We have a system (algorithm, function, circuit, program, etc.).
  • The system operates within different contexts/environments.
  • In Context A, it must produce a desired output.
  • In Contexts B, C, D..., it should not produce that output.
  • The context may interact with or modify any part of the system.
  • We are free to modify the system itself.
  • The system can be enormous in complexity, but ideally is optimized for minimimum required complexity that might scale with the number of contexts.
  • The contexts can also be enormous in complexity and interact with the system in many ways.
  • Some internal components are essential for producing the desired output in Context A.
  • Other components are free to change.
  • The problem is that we do not know which components are essential and which are not.
  • We can only evaluate the system by observing its behaviour in each context.

Are there existing computational methods that tackle this type of problem?
