We have all this data available here if anyone wants to use it. Click the download button to get a local copy in csv format. We'll run our own monte carlo analysis later today using various models and post it here, along with some regression analysis on which model gives the most accurate predictions, just for fun.

Thanks!

Re: 2015 Championship division simulated rankings
 

Wow, thanks!

Re: 2015 Championship division simulated rankings
 

Just to verify: the "Highest OPR (no co-op)" column includes auto?

Re: 2015 Championship division simulated rankings
 

I see our team is ranked last in Newton. :-( Well, with 118, 1671, and 1678 in Newton, we are definitely a division to watch. All these powerful alliances are going to be looking for a match proven cheese caked can burglar (I hope).

Top alliances with a landfill stacker, a human side stacker and a can burglar are going to be fun to watch. A bonus is a can burglar who can add functionality by stacking or manipulating flipped over totes and cans, or fill in if a top seed malfunctions.

Re: 2015 Championship division simulated rankings
 

Yes it does; If you'd like to do what CVR suggested you'd take the "Highest OPR (no coop)" and subtract the auto OPR.

Re: 2015 Championship division simulated rankings
 

Perfect. I updated my website to use this new algorithm: championship.evanforbes.net

Re: 2015 Championship division simulated rankings
 

Can I just say, thanks to Jeremy for the simulation, 955 for the really nice applet and breakdown OPR for every team and event, and to Evan for his awesome Championship website. All this stuff is really cool to look at, and we appreciate it.

Re: 2015 Championship division simulated rankings
 

There's an issue with this method that may skew predictions for alliances with more than one team that does a lot of co-op. Lets say:

R1 has a "platform OPR of 40, and a co-op OPR of 30
R2 has a "platform OPR of 40 and a co-op OPR of 28
R3 has OPRs of 0 for the sake of argument

By the above method, the red alliance would be predicted to score just 110 points, since we would use R1's co-op average, but not R2's. But if R2 can usually score 40 platform points *and do co-op most of the time*, surely they wouldn't put up their 40 and then spend the rest of the match twiddling their thumbs. They would use the time they normally use on co-op to score more platform points!

(There's also the issue of whether the opposing alliance has a high enough Co-op OPR to ensure co-op will be successful, but now we're getting really complicated.)

Re: 2015 Championship division simulated rankings
 

Is the max coopOPR used for the same event as the Max OPR? If not I see some problems where it may appear that teams score more than they really do, if they coop more at some events, and then stacked more at other events. They would be getting the max points from both.

Re: 2015 Championship division simulated rankings
 

On the coop OPR I think you need to take a sum of the maxBlue(coopOPR,20)+maxRed(coopOPR,20) as the closest approximation and apply the total to both alliances.

And watching the regionals, the coop points increased with overall scores so that the max coop OPRs should be in an event close to the max OPR.

Re: 2015 Championship division simulated rankings
 

I think you would want to take a sum of the min(max(BluecoopOPRs),20)+min(max(RedcoopOPRs),20) , as what you wrote would just give every alliance 40 points.

Re: 2015 Championship division simulated rankings
 

I would like to get a copy of this source code before CMP if possible, so I can play with it while on the plane.

Re: 2015 Championship division simulated rankings
 

Here is the source Netbeans project that I used to run the simulations along with all of the data files I used. Thanks to Evan Forbes and his website for providing me with a source for the best OPR data.

I may rework the randomization model code tonight as the model used for simulations was a very naive version.

Feel free to PM me with any questions.

Re: 2015 Championship division simulated rankings
 

So, statistically speaking - it is proven that never in 10,000 years, will 254 not finish 1st in their division. I don't think that would have happened with any other game under the exact same algorithm.

Does anyone know how to run the same algorithm, for say last year, and see how close it is to actual results?
