My AI analys

[Matte979]

The AI.

I have messed around with the Strategie files mainly to get the AI more aggresive.

I found the big problem. The AI needs to be bigger than you to attack. Also the AI needs alot of units to spare. The AI needs higher priority on attack.

I have done the following changes.
1. First the priority of Attack has been lifted in the strategies file.
2. The amount of support was raised

3. The build offence and build defence has been raised defence to same priority as growth (the highest before)
and offence to the one step below. for example 10000 and 9000.

4. The support cost for all middle game units have been lowered. Specilly all defence units halfed the support cost atleast.

5. Added higher bonus to production in diffdb

6. At the Goal attack and Goal siege i added target coldenemy so it will look for opertunites everywere.

7. Lowered distans modifier to 10-25

8. Lowered the force compare numbers some. Not sure if this part is good, some really stupid attacks. (But again thats like how CIV 2 was.


Preliminary Result: Alot more units for the AI and the defence part will quickly be reach and then the AI will build alot of offensive units and they will use them. Looks very promising. My weak cities is attacked.

Conclusion. The AI needs more units, And needs higher priority to attack. The first is the most important part.

If anybody else could try this and see the effect it might solve the problem of AIs not attacking.

Looks good - I printed out your post on this and I will refer to this when I get the courage to make the alterations you suggested.

Thank you for your research. I've had big problems with the standard AI behavior too.

First Question: Is it possible, to publish your strategies.txt in this forum?

Second Question: Modify the changed txt-files old games too, or must I start a new one?

Thanx, Andre

I seem to get affect in save games so you can try to change and then test and then save, change and test and save. Thats how I found some of the problems.

The strategies file is to big to post here. I can post the first default strategy as mine is configured and you will get the idea what i have changed.

Made some other changes aswell. For example don't like the new diffrent specialists so have removed all but entertainers and scientists.
