As Computer Science struggles to understand the Internet and its capabilities, computer scientists are incorporating concepts and methodologies from Economics and Game Theory into their discipline. In the past decades, there has been a tremendous growth in research, centered around the following questions: What game-theoretic tools are applicable to computer systems? How far is the performance of a system from optimality due to the conflict of interests of its users and administrators? How can we design a system whose performance is robust with respect to the potential conflict of interests inside the system?
The course aims to tackle some of the fundamental problems at the interface of Computer Science and Game theory, with an emphasis on algorithms and computational complexity. Our main focus will be on algorithms for equilibria, the computational complexity of finding equilibria, the algorithmic tools in mechanism design for auctions, the stategic behavior models for large networks, and the price of anarchy. Incorporating also some notions from cooperative game theory.

There will be two kinds of classes: theoretical sessions and practical sessions. On average, two hours per week are dedicated to theory and one
hour per week to exercises. The teacher will allocate the hours in accordance to the subject matter.
The theory classes take the form of lectures in which the teacher sets out new concepts or techniques. Those are complemented with examples illustrating the introduced concepts. 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 carry out exercises in which students take an active part. Usually teachers set the exercises in advance. Students are
required to submit the exercises and then discuss the various solutions/alternatives in class.
C1 , C2 = Graded in-class assignments. Each one is graded from 0 to 10.
FW = Paper presentation (graded from 0 to 10) in which each participant is required to present a research paper (previously assigned by the lecturer).
The presentation consists of:
3-5 minutes background on the topic of the paper, and motivation.
1-3 minute overview of the key ideas of the paper.
10 minutes presentation with most important details.
2-5 minutes conclusions and review of research problems or directions left in the paper.
FT = Final test graded from (0 to 10) including all the contents of AGT.

Basic knowledge on algorithms. Linear Programming. Maximum flow. Local search. Graph and Network algorithms.
Basic knowledge on algebraic reasoning.
Basic knowledge on computational complexity, classes and reductions.
