Teaching the course is organized in two teaching cycles. The first cycle contains seven weeks, mid-term exam, and the second cycle contains six weeks of classes and a final exam. Classes are conducted through a total of 15 weeks with weekly load of 2 hours. Each lecture includes wrriten material and slides.

Solved examples to support lectures and prepare students for exams. 1 hour per week. Solved examples on slides and discussion of possible variations in problem statement with examples on board.
