AILien’s learning turned out to be non-existent in the AIIDE 2017 version. It writes files but does not read them back in.

Here is AILien’s recorded data from AIIDE 2017 for the opponent XIMP.

lingScore=24.4783
hydraScore=-4762.48
lurkerScore=0
mutaScore=-904.381
ultraScore=-1757.08
guardScore=0
macroHeavyness=0
supplyISawAir=149
strategy=17
victory=false

The first six lines are information about what units to make, as updated during the game. macroHeavyness and supplyISawAir are updated but I didn’t find any sign that they are used for anything; I think they were used in a former version. strategy likely used to be an index into the unused GameCommander::strategyMap, but no matter what it originally was, now it is a constant. And victory is the result of the most recent game. As I said at the start, the information is written out but is never read back in.

Next: Those tscmoo games I promised last month.

AILien scored a fine win over XIMP. The game plan to defeat Tomas Vajda’s carrier bot:

1. Take 7 bases and grow a huge economy.
2. Prevent XIMP from expanding beyond its natural.
3. Don’t bother to fight the carriers, just accept losses. With enough units on the map, the carriers chose to destroy defenseless zerg units to protect protoss bases and did not visit a zerg base until too late.
4. When hive tech is ready, adrenal glands for the zerglings and the ultralisk upgrades, go win. Zerg can send units faster than protoss can kill them.

Ha ha, so simple! AILien made hydralisks, but I didn’t see them fire a shot against carriers or interceptors. That would have been too easy! No, XIMP is not properly put in its place unless zerg handicaps itself with buggy hydras!

I’m too busy to pull images, but watch the replay at the link. Let’s see how long the replay stays online.
