Re: [FiM] MSC Division Selection Process

You Hurd it here, FIRST!

Seriously, Jim's thoughts on Signal-to-Noise are worth reviewing. I am looking forward to the analysis of MSC divisions.

Re: [FiM] MSC Division Selection Process

I mean, it would be nice if there were actual details, but I guess we don't know any more than we know about the algorithm that schedules our matches, so whatever..

Re: [FiM] MSC Division Selection Process

Agreed. Ambiguous at best. So it's a "controlled" randomness?

Re: [FiM] MSC Division Selection Process

Michigan Teams
I would like to bring a little clarity to this new process.
Our Michigan Championship is now so large that we need to divide it into divisions, much like the World Championship did back in 2001.
We wanted a process to do this easily, fairly, and automatically.

Dan Kimura and I have developed the process for dividing the MSC Divisions.
We have developed a program to perform this function automatically; there is no human intervention.
We have reviewed this process with Frank Merrick and other technical members of the HQ staff and received their approval.

The previous statement of "controlled randomness" is correct.
The makeup of the members of the divisions is indeed random; however the program guarantees strength balancing between the four groups.
We use the state ranking points as the measure for these comparisons.
The program is iterative; it will randomly create candidate division sets and will analyze and reject them until an acceptable solution is found.
Three different statistical measures are used to determine a passing solution.

A Simplified Process flow diagram is below



Shortly following the conclusion of the week 6 events, invitations to MSC will be extended to the teams.
Once a complete set of 160 accepting teams is solidified, the division lists will be generated by HQ and communicated to the teams.

Good Luck to all teams at the 2017 Michigan State Championship

Re: [FiM] MSC Division Selection Process

Thank you, Jim, for the explanation. I think the task of coming up with fair, balanced divisions is a super interesting one and I'd love to know more about the MSC solution. Can you elaborate a bit on the process of computing the signal-to-noise ration and deciding how to determine the cutoff for acceptable signal-to-noise?

Re: [FiM] MSC Division Selection Process

Thanks for the clarification. That seems like a lot of unneeded calculation, although that's not a disaster or anything. I'd just generate the divisions a bit more intelligently / less randomly. You could iterate through the divisions (serpentine style), with some distribution determining the probability of which team gets added. For example:
50% the highest seeded remaining team gets added
25% second highest seeded remaining team gets added
25% third highest seeded remaining team gets added

You'd end up with more balanced "draft" divisions, and would probably have to generate a lot fewer before finding an acceptable one.

Re: [FiM] MSC Division Selection Process

Many thanks to Jim and Dan for working this out. Any reasonable attempt to distribute talent should be beneficial to all.

Since the 160 teams receiving invitations have been so prompt in letting FiM know whether or not they plan to accept (reportedly only a handful have not responded as of mid Monday morning), is there any chance that the division assignments will be announced before Tuesday evening?
