Computer evaluation

Is it possible to evaluate how complicated position is with an algorithm of some sort? Wouldn't it be interesting to see how you can complicate a position or defuse tension? Were there any attempts to create an engine capable of evaluating more than just one number? Maybe with neural networks?

The closest thing that I can think of that even comes close is the Fritz Hotness meter, but that even isn't that close. It seems like more of a gimmick than anything but sometimes it's interesting to see what it says about a position. Here is the link.
