Heal or penalize invalid individuals

[vicdoja]

As the course's professor told me: when an individual suffers from a condition 🤒, it may heal 💉, get handicapped 🤕 or die ☠.

I don't like the dying approach, so don't get me near any of that stuff. In our case, every individual has the potential to become the fittest one 💪, so we must try to either heal 🏥 them or penalize 🎃 their fitness.

Note that this may help with the covering issues of the linear tree ➗.
