2013 Qual Schedule Analysis

[MikeE]

A few points.

There is a description of an early version of the scheduling software on the Idle Loop website. The FMS may use a more recent version but let's assume the algorithm is the same.

The scheduling algorithm is stochastic, i.e. it has a random element to it, which is a standard approach for solving a complex optimization problem.
The particular criterion discussed above is "Pairing Uniformity" and it is one of the goals being optimized, but that has to be balanced against several other criteria including computation time.

Since the algorithm is stochastic, the "good schedule" metric isn't really do the same teams play with/against each other more than once but rather does this happen much more frequently than we expect.

Smaller events such as Western Canada or Toronto East have few enough teams that it's a mathematical necessity that the same teams face each other more than once.

Finally, most Regionals have 1-5 teams who play an additional surrogate match. If the purpose of this analysis is to see how it affects ranking then a team's surrogate match should really be excluded, although they would still count as a partner or alliance for other teams. (This is a small effect)

At the Livonia district, we had to go against Team 27 in three of our first four matches during qualifications. We also played with them once in our last match of qualifications. It just seemed that the scheduling algorithm should have prevented something like that from occurring.

Ok maybe I am just not getting it what is the difference between W and A and what does each number in each mean

EDIT: Wait Senior moment W is With and A is Against? and the numbers are the occurrences
