I keep hearing about an “algorithm.” What is it and how does it work?

An algorithm helps Enroll Indy match students to schools, using their preferences, the school’s priorities, and their random lottery number. The algorithm helps Enroll Indy do the very complicated math of assigning thousands of students to thousands of school seats. The algorithm does NOT change a student’s preferences or priorities. It also does not recommend schools to students. The algorithm used to assign students was built by a team of Nobel-prize winning economists. The results of the lottery will be independently evaluated.
