what's your question? be descriptive.

By: [ Editor ] Asked from Sweden

Artificial intelligence in EVE online

Are there any resources on analysis of behaviour of EVE game-AI (regular, sleepers, in/out of mission, whatever) and how it works and what affects it? If there isn't a deep scientific analysis maybe there exists more light reading about behaviour?

Or... feel free to write your own subjective experiences or scientific data gathering, analysis and conclusions right here. A good post should state sources or what they base their conclusions on. Please also link any abbreviations, items etc to wikis.

Do you mean regular AI ? Or Sleepers ?

As far as I know, regular NPC controller AI is pretty basic

  • Spawning an entity in an asteroid belt you warp to, or when triggered by a deadspace complex mechanic.
  • Picking a random target as a group or in response to a deadspace complex trigger.
  • Using whatever effects available to them on the chosen target.
  • Warping out of the encounter area when in danger (does not apply to missions).

When it comes to sleepers, it's a different story.

The upgraded NPC controller is much more efficient at kicking you in the face, namely :

  • Picking an optimal target based on dynamic criteria.
  • Picking a secondary target for effects, based on dynamic criteria (applies to both friendly and hostile targets).
  • Using remote assistance on each other.
  • Using evasive maneuvering when approaching their chosen target from a large distance.

While regular AI will aggro you based on you shooting them, coming into aggro range or triggering their group by shooting something you should no...

Sleepers AI is much more dangerous because they will change target if they feel the need to. I couldn't find data regarding this, but there were complaints from drone users that their drones where disposed of by sleepers very fast.

On a more general notes, there were some complaints about sleepers being challenging only because they were cheating :

  • super Fast lock
  • Extreme ranges of their webs, scrams and other EWar
  • Neuting ability on their weapons
  • Extreme damage output

That's no maths, but at least it's a start ;)

They seem to favor what they can destroy fast, rather than regular AI almost never changing target once they aggro. As such sleepers fight cannot be : warp in tank, aggro, warp the fleet, pew pew with no problems.

Also note (thx Nathan Cox for this) Sleepers do omni damage, and like you said they do target drones and logistics. PVP tactics should be used against sleepers, not PVE. Anything that would make sense for you to do in PVP, they will already be doing to you

Thanks Harlock, that’s a nice intro before venturing further into the maths, specification of “dynamic criteria” etc. I never seen the abbreviation IA before. What’s that?

Picking an optimal target based on dynamic criteria.

In the words of Marr, “To be sure, but how?!”

I’ve figured out how I would do some of the AI for a small-group engagement, and but I haven’t had time to write up my notes for the EVE community.

IA is the french version of AI ;) Intelligence Artificielle == Artificial Intelligence. Sorry for the confusion ;)

Adding this to my reply if you don’t mind ;)

Great answer. Remember that the same Sleeper mechanics will apply to at least the same degree if not more with the Sanshas of the Incursion. I have a feeling that if Incursions go the way CCP is hoping, we’ll be seeing a lot more of the Sleeper AI outside of whs, but that’s just a theory.

It’s a bit troublesome for drone users though, because due to superfast lock and huge tracking sleepers are super deadly against drones… basically light drones will die in seconds if further away than 10 km… medium and heavy are more resilient but slower as well…

After spending a few days in a class 2 WH, I couldn’t find any logic behind the sleepers behavior. They seem to change target at random. But usually their focus is deadly and perfect : they ALL chose the same target at the same time. Don’t know what happens with large fleets, there where two of us when we tried.

I remember seeing some discussions here (or somewhere else ? damn memory) about the pace at which sleepers did change target. As far as I remember, pretty much everybody had different numbers. CCP did a great job at bluring it’s tracks and obfuscating game mecanics when it comes to those sleepers AI… I am fairly sure there is a good fair use of /random in timers to make things as troublesome as possible for us to figure out.

Their unpredictable behavior and their firepower makes it’s difficult to put them in a situation you can replicate and compare.

This is a great answer, this is the mechanic that CCP describes in the old blogs. However I have a sneaky suspicion that normal NPC’s aren’t random in there target selection. It may be ship class dependant, distance dependant, role dependant, or even name dependant I have no idea. Me and a group of 5 mates tested this in an evenings anomming, my alt who is in an untanked salvage hurricane was primaried 92 times out of 130 spawns out of 8 characters on grid with us. He spent all his time warping away pretty much, i now fit a cloak to save the warping.
