EDIT: Isomorphic used in the sense of the event ("boycott", cheating) being similar in form/geist to the class taken. I'm sure there's a better word for it.
Andrew Kelly, a student in Fröhlich’s Introduction to Programming class who was one of the boycott’s key organizers, explained the logic of the students' decision via e-mail: "Handing out 0's to your classmates will not improve your performance in this course," Kelly said.
This is actually not an interesting problem from the game theory perspective: defection gains you nothing. That is, if you're the only person who defects, your situation is the same if no one had defected. I'm assuming here that the grade curving is local to the assignments. Handing out zeroes to your classmates will help if your overall number of points goes up, and overall number of points in the class determines final grade.
*quickly looks up the definition of 'isomorphism'*
Find isomorphisms at great prices!
1. Biology: Similarity in form, as in organisms of different ancestry.
2. Mathematics: A one-to-one correspondence between the elements of two sets such that the result of an operation on elements of one set corresponds to the result of the analogous operation on their images in the other set.
3. Chemistry: A close similarity in the crystalline structure of two or more substances of similar chemical composition.
