Thursdays, 12:00 - 15:00, in the seminar room
A set of home assignments will be given approximately every 2-3
weeks. The grade is combined as follows: 80% based on the exam and
20% on the homework. All the works submitted by the students will
be checked, so that the grade on the homework part is an average
grade on all the problem solutions that have been submitted.
