Annotation

Required course for bachelor's program in Information security. The course contains description of algorithms used in computer systems for symbolic manipulation.

It begins with analysis of the simplest algebraic algorithms and shows how to use theoretic results for their improvement. Algorithms for polynomials over integers, rational numbers or finite fields are emphasized.
