It has happened to all of us. We go full-speed to get a tech so we can sell it to all the AIs and get rich, only to find that some AI is also researching the same tech, gets it before us, and sells it to everyone. Wouldn't it be nice to be able to predict what technology the AI will research next?
Well, after reading this post, you can at least have an idea of the AI priorities.
The AI places a value on each technology it can research next. The values depend on the various things allowed by each technology, as well as on the turns needed by that AI civ to complete the research. Here are the values:
SS Component: 261/turns
Government: 259/turns
Conscription: 259/turns
Mobilization: 259/turns
Defender (no resource): 198
Attacker (no resource): 134
Defender (resource reqd): 70
Naval Transport: 34
Resource: 16
Double Worker Speed: 8
Allows Diplomats: 8
MPPs: 8
ROPs: 8
Alliances: 8
Embargoes: 8
