Math CentralQuandaries & Queries


Question from Dusty, a student:

Ok, Im trying to create a rotating schedule. There are four jobs and four people but, one of four people cant preform one job. How can I figure out a rotating schedule for this issue?


Try this. Assume everyone can do every job and make a rotating schedule. Repeat it three times. Each time the person unable to do that job gets it, swap jobs with one of the other three. With three repetitions, this can be done so each of the other three people gets that job exactly one more time. After all the swapping is done, this schedule can be used over and over.
