This book constitutes the proceedings of the 5th International Computer Science Symposium in Russia, CSR 2010, held in Kazan, Russia, in June 2010. The 30 papers presented were carefully reviewed and selected from 62 submissions. The scope of topics of the symposium was quite broad and covered basically all areas of the foundations of theoretical computer science.
