Metodologia docent
The lectures are theoretical/practical merged sessions.The lecturer will allocate the hours in accordance with the subject matter.
The theory hours take the form of lectures in which the lecturer sets
out new concepts or techniques and examples illustrating them.
Sessions will consist of a presentation of the main topics of each content's item,
mainly based in selected original research papers.
A high level of students' participation is expected at each session.
Current lines of research in each topic will be discussed at the end of each topics' presentation.
The practical classes are used to explain implementations and show the performance of selected data structures.
Students are required to take an active part in the class by
discussing the various possible solutions/alternatives in class.
Mètode d'avaluació
The final grade F is calculated using the following formula:F = 0.5 (VE) + 0.5 ((P1 + P2 + P3 + P4) / 4);
with:
VE = exam (0--10 points), P_i = programming project (0--10 points), i = 1,2,3,4
