The information on the semester allows us to define an ideal path and to compare it 2-Deoxy-D-glucose with the path of a generic student. More precisely, we consider a database containing the data of N graduated students, each student characterized by a sequence of n exams identifiers and a particular path I=(e1,e2,…,en)I=(e1,e2,…,en), the ideal path, or ideal career , corresponding to the ideal student who takes every examination just after the end of the relative course, without delay, before graduating. Since in the same semester there are many courses, the ideal path is not unique. In human chorionic gonadotropin (hCG) paper we consider courses relative to the same semester sorted according to the preferences of an expert of the university domain; for example, this choice may depend on the content of the courses or on the order preferred by students in taking the exams in the same semester. Without loss of generality, we can assume that ei=i,i=1,…,nei=i,i=1,…,n, that is, I=(1,2,…,n)I=(1,2,…,n) coincides with the identity permutation of integers from 1 to n.
