The objective function (Equation 66.1) assures that credit assignments are balanced between
semesters.
The constraint (Equation 66.2) ensures that each course is assigned to exactly one semester. A
course cannot be given before its prerequisite courses (soft prerequisites), which is expressed in the
constraint (Equation 66.3). In a similar way, constraint (Equation 66.4) encodes hard prerequisites.
Finally, constraint (Equation 66.5) xes the number of credits per academic year.
