Choice of Treasure Chests bonus for the AI hero, and Tree of Knowledge

[LeHerosInconnu]

In fheroes2, I noticed that the AI often has a lot of unbought creatures in his captured castles.

In fheroes2:

And looking at this, I thought that maybe it should be a bit more elaborated:
"- a chance to choose experience from treasure boxes reduced from 50% to 10%" (#3692)

The Treasure Chest can give:

• 1000 gold or 500 XP
• 1500 gold or 1000 XP
• 2000 gold or 1500 XP

Experience Points needed to reach the Hero Levels (1 to 11):

Level XP
1 0
2 1000
3 2000
4 3200
5 4500
6 6000
7 7700
8 9000
9 11000
10 13200
11 15500

Here is how a hero could behave after some thoughts:

• The hero should never take the 500 XP (the ratio is too unfavorable), unless it allows him to level up (and possibly if there are no other treasure chests nearby).
• The hero should take the 1000 XP and 1500 XP only if the hero has a level less than or equal to 10, or if it allows him to level up.
• The hero should take the 1000 XP and 1500 XP only if there is enough gold to build the desired buildings in the castles and if there is enough gold to recruit the desired creatures, and if there is enough gold to recruit a necessary hero.
• It should also be taken into account whether the hero is one of the player's main heroes or only an expendable hero (like a scout or a scavenger for example).
• And maybe we should also take into account the personality of the AI player (Builder, Explorer, Warrior).
• Also, regarding the hero's experience and Trees of Knowledge, the hero should visit them only when he has reached a high enough level (e.g. after level 10) and provided that the cost, if any, does not penalize the construction of an important building.

Also, does the AI always choose gold in the treasure chests in original game?
