Abstract

The Oregon School Activities Association (OSAA) is a private, non-profit, board governed association comprised of 291[1] member high schools. The OSAA, sanctioned by the Oregon State Board of Education and a member of the National Federation of State High School Associations, annually sponsors 80 state championships in 16 sports and activities.

The association needs to set the classification and league membership for interscholastic high school sports in the state due to changing population demographics and other factors. The OSAA needs to realign both the leagues and classifications to adjust for these changes. The needs of the schools, including travel expense and traditional team rivalries within the current alignment need to be considered during classification.

The study “OSAA: Football League Assignment”[2] conducted gives a mathematical solution to this assignment problem. In the current project, I have converted this mathematical model into R, by application of various R concepts. I have also done a comparative analysis of various solvers in R, such as GLPK, Symphony and Gurobi.

The OSAA currently sets two levels of competition within the state: the classification and the league. These are defined as follows: A classification is composed of high schools of similar size throughout the state. There are, currently, six classifications: 6A, 5A, 4A, 3A, 2A and 1A. All 6A schools have average attendance above 1260 people. Within each classification, leagues are established for localized competition. For instance, the Portland Interscholastic League (PIL) is made up of high schools within the city limits of Portland.
