1. Back to basics: What is intelligence?
Without being exhaustive, an unambiguous, fundamental (=natural) and deterministic (=implementable) definition of intelligence is used:
Intelligence is the capability of autonomously associating, discriminating, learning, planning and predicting, with the aim to reach a predefined goal.
More into detail:
• associating (or combining) of individual or separate objects, with the aim of achieving a goal that can not be achieved by either of those objects separately;
• discriminating (or differentiating) compound or intertwined objects, with the aim to clarify the situation, by putting them in their own context;
• learning is using knowledge and experience to differentiate successes from mistakes;
• planning future actions to achieve a goal;
• predicting possible consequences of those planned actions.
Initially, the associating and discriminating capabilities will be implemented, see 3.3 Semantics.
