    Hmmmm....
    Well, in theory one should only need the AI lap-time for one specific AI level, and then you should be able to adjust from there.
    Example: if the 100% AI runs a car/track combo in 80 seconds and you do it in 73, you should be able to start around level 109-110.
    80/73=109,5
    Again, in theory. :D

    Yep, confirmed.
    That actually works rather well.
    100% AI laptime divided with my own yielded 101,8 so I set it 102 and got a good fight with no new index written.
    So if you're unsure of your level, run one lap with 100% AI to get a lap-time.
    After that you can simply divide and conquer (if you'll pardon the atrocious pun :D )

    Great info. Tomorrow i'l begin to record AI lap times for all tracks and cars i have :)

    Don't forget to include the AI level as well. Otherwise the info will be useless.
    Come to think of it, the easiest way would be to simply upload a copy of your adaptation-file.
    Here's mine: http://www.mediafire.com/download/klledr99jprfu4z/aiadaptation.xml

    @mr_belowski you stated earlier that your adaptation-file was full of stuff.
    Any chance for a copy of it?

    Sure, but it'll be tomorrow evening now.

    Had a few thoughts about this process too, which I'll arrange in a sane order and write down :)

    I can help parsing the stuff with some scripts and create a database file.

    So we don't need to train the ai now?

    Well the data doesn't come from nothing, ideally we can quickly generate something that makes "priming" files quicker.
    You'd still need to know what lap times you typically do, per class per track

    Think of a tool that let's you enter track and class and desired target time + variance. Then generates the adaptive file for you.

    The tool works better the more people provide their current adaptive files.

    I should probably try that at some point. :D
    Well, we do. What we're trying to do is figure out an automatic way to get it started at the right level.
    The larger your variance in your lap-times, the more levels you're going to need in the XML file.

    Great thread! Question... what is the effect of off-track/invalid laps on the competitiveness of the AI. If I have, say 2 invalid laps out of 10, and the 8 valid laps are consistent. How much will that affect the AI in the next race?

    You could, but if you're going to run one lap anyway you might as well do it with AI and get the index written automatically.

    Just wanted to say that I tried @CheerfullyInsane 's AI training last night, and it worked perfectly. Did a bit of a qualifying session against a 100% AI to get my AI level (was down by -0.5s, so 100% :p ), did my six laps to get the 98-103 indices, then started a 20-car race against the Adaptive AI. Started P10, worked my way up to P4, was nose-to-tail with P3 for a couple of laps trying to pass, then spun on the penultimate lap, finally recovering to P8. Great race!

    It seems to me that an AI training mode could/should be part of the game. For one thing it would clear up new player confusion about adaptive AI seemingly not being any use. I understand priorities and resources and rejiggering the menus and testing all that, but conceptually at least it's pretty straightforward. Step 1, have the player pick a car and track, then go out and do as many laps as they like against a ghost AI at 100%. When the player has a lap time they're satisfied with, they can continue to step 2, six laps against a ghost AI at (AI's step 1 lap time / player's step 1 lap time) - 2%... etc. Done! I am not a developer, but that doesn't seem too infeasible.

    And they can add Apex Hunt back while they're at it. :D

    Could be done a lot easier.
    Simply have the AI write an index for every lap, instead of after each race. That way you'd get a working index after one 30min race.
    But then, I'm not a programmer either so what do I know? :D

    Hm, following this thread since days, I decided to give the adaptive AI a second try. Its long time ago I tested this feature, and it was when I had far less hours with raceroom under the belt.

    Honestly said, something has changed - for the better. I do not kn ow whether it is the feature itself, that they have tweaked it, or if it simply is me and my perception now, today, but having had several 10 minutes races with randomised time of day and starting positions and always default car setups, no training and no quali sessions, after just three races had me racing against GT3 cars, later also GTO cars and DTM2015 cars, that indeed had nicely adapted to my own skill level. It works much better than I recall it did last year, in summer, or whenever it was.

    So I am happy to admit that I cannot hold up my former opinion anymore that the feature did not work too useful. It does, and I really like it now. Whether it is a change in me, or a change in the code, I cannot say.

    At least my needs are well served with it.

    I'd like to know, however, how it works if you set up a championship. Will the AI still make small changes from race to race, or will it use one and the same AI setting found by the adaptive AI at season start for the whole season?

    If it is longer time ago, many months, you tested the feature yourself in SP, give it another try, maybe, just two or three short races may be enough to make things klick right for you. Just make sure you do not mess up your result by crashing, spinning off, but do a clean race and finish.

    My apologies to S3 if I ever criticised this feature in the past in harsh words, while the adaptive aI ha dnot been changed in this time indeed. I do not remember that I ever became harsh in words over this feature, but memories may have escaped me.

    P.S. Before, I used fixed AI at 100, 110 or 120% (with default car settings), depending on car class.

    Hi !

    I spend a lot of time to find this file but i can' find it ? I drove with Adaptive AI a lot of time.

    Whats wrong with my game ?...

    The file is in "Documents\my games\SimBin\RaceRoom Racing Experience\UserData\Player1\aiadaptation.xml".

    Sorry for the late reply, I must've missed that one.
    Anyway, championships work exactly the same as normal races when it comes to the adaptive AI.
    It doesn't set an AI level for the championship as a whole, it simply uses the indexes already saved for each car/track combo.
    So if you're at around 98 on one track, it'll use that, and maybe switch to 109 on the next track if you're better at that particular piece of real estate.
    The upside is that you don't have to be equally good on all tracks (and I don't know any who are).
    The downside of course is that you have to train the AI for each track before starting the championship.
