**Intelligence** is efficient cross-domain optimization [1]. It measures an agent’s capacity for efficient cross-domain optimization of the world according to the agent’s preferences [2]. Optimization measures not only the capacity to achieve the desired goal but also is inversely proportional to the amount of resources used. It’s the ability to steer the future so it hits that small target of desired outcomes in the large space of all possible outcomes, using fewer resources as possible. For example, when Deep Blue defeated Kasparov, it was able to hit that small possible outcome where it made the right order of moves given Kasparov’s moves from the very large set of all possible moves. In that domain, it was more optimal than Kasparov. However, Kasparov would have defeated Deep Blue in almost any other relevant domain, and hence, it is considered more intelligent.

One could cast this definition in a possible world vocabulary, intelligence is:

- (1) the ability to precisely realize one of the members of a small set of possible future worlds that have a higher preference over the vast set of all other possible worlds with lower preference; while
- (2) using fewer resources than the other alternatives paths for getting there; and in the
- (3) most diverse domains as possible.

How many more worlds have a higher preference then the one realized by the agent, less intelligent he is. How many more worlds have a lower preference than the one realized by the agent, more intelligent he is. (Or: How much smaller is the set of worlds at least as preferable as the one realized, more intelligent the agent is). How much less paths for realizing the desired world using fewer resources than those spent by the agent, more intelligent he is. And finally, in how many more domains the agent can be more efficiently optimal, more intelligent he is. Restating it, the intelligence of a agent is directly proportional to:

- (a) the numbers of worlds with lower preference than the one realized,
- (b) how much smaller is the set of paths more efficient than the one taken by the agent and
- (c) how more wider are the domains where the agent can effectively realize his preferences;

and it is, accordingly, inversely proportional to:

- (d) the numbers of world with higher preference than the one realized,
- (e) how much bigger is the set of paths more efficient than the one taken by the agent and
- (f) how much more narrow are the domains where the agent can efficiently realize his preferences.

This definition avoids several problems common in many others definitions, especially it avoids anthropomorphizing intelligence.
