The problem sets are not marked and their completion is completely voluntary. The problem sets are designed to help the students get a better grasp of the material and to prepare for the test and the exam. The lecturers will post on the web written answers or answer guides to the questions and some answers may also be discussed during the lectures. Any situation in which a decision is influenced by other peoples' decisions involves strategy. A country's decision on how much money to invest in training its athletes involves strategy because the payoff of that decision, e.g. the number of medals in the Olympics, depends on how much money other countries spend on their athletes.
Warfare involves strategy because the outcome of a war depends on the decisions made by the enemy.
Decisions made by business managers involve strategy because firms' profits depend on the rivals' decisions. Politics, parenting, dating and studying all involve strategy. In fact, it is hard to come up with examples of situations that do not involve strategy. This course teaches basic concepts and principles used in analysing strategic decision-making. The science of strategic thinking is called game theory .
