Great talk, not specifically about AI but in general about programming. Especially documenting intent that's something that's missing way too often.

Oh wow Ive had both of the problems described here on my game, so they are very much real practical issues. I fixed the optimal attack distance by having a range, say the enemy wants to be between 0.5 and 1 units away from you and when it asks for a position it asks at the middle of this range, so 0.75 units away from the player, this way you get consistent attacks when you cross the 1 unit distance barrier (super necessary for melee combat). Problem two required an AI director, that takes information from the enemies on the field and picks one to engage then I use a table to calculate when to switch to another enemy (after the engaged enemy has attacked, or been hurt, or enough time has passed)
