Grading
There will be no exam for this course. In turn, 6 problem assignments willbe proposed during the course (two for each section). From all of them, eachstudent will be free to choose a subset covering at least 75% of the total. Gradingwill be based on this subset only. Students who desire to hand a report for morethan this percentage are of course free to do so.
