It will be useful to consider the assignment of students on the basis of their types. A vectorx [(x t,s) ∈T,s M] is called a type-assignment if for every type t ∈ T, ∑ s∈M x t,s C t. Note that every assignment cor-responds to a unique type-assignment. Throughout the paper, we will refer to a type-assignment simply as an assignment.
