So it&amp;#x27;s not really fair to call it 5 separate minds.&lt;p&gt;You can&amp;#x27;t really call it a single mind either because if you assume the LSTM is the &amp;quot;mind&amp;quot; (since it&amp;#x27;s the only place that has memory of previous state), that state isn&amp;#x27;t read by any other bots.</text><parent_chain><item><author>shawn</author><text>As someone who was once semi-pro in dota (4400 MMR, get rekt), it&amp;#x27;s &lt;i&gt;freaky&lt;/i&gt; watching these bots play.

The training contained lots of little &amp;quot;nudges&amp;quot; to reward the bots for things that lead to winning. I.e. there are nudges to get them to go to lane to start, there are nudges to get them to buy the right items. I don&amp;#x27;t know for sure but I wouldn&amp;#x27;t be surprised if they kill the ranged barracks first because there&amp;#x27;s a built in reward for killing barracks that&amp;#x27;s the same for both melee and ranged barracks but the ranged ones have less health so they value that a little bit higher since it&amp;#x27;s a more consistent reward than trying to get the melee one. I hope that someday they get to a point where they can truly train from scratch with no human nudges, I&amp;#x27;m not sure how much more impressive of an ML result that would be (I&amp;#x27;d imagine meaningfully so but I&amp;#x27;m not an AI researcher) but it would certainly be a much more interesting result in terms of our understanding of DOTA.</text><parent_chain><item><author>shawn</author><text>As someone who was once semi-pro in dota (4400 MMR, get rekt), it&amp;#x27;s &lt;i&gt;freaky&lt;/i&gt; watching these bots play.
