Course objectives

Abstract machine models of computation - the Turing Machine and the RAM - are introduced. The concept of machine computability is built on their basis. The existence of non-computable problems is proven and their examples given. In the second part of the course, asymptotical time and space complexity of algorithms is introduced. This allows to describe the consumption of time and space of algorithms without fixing to any particular computing machine. Elementary complexity classes and their properties are studied, with special emphasis on the classes P and NP.
