This volume gives the proceedings of the Tenth Conference on Foundations of Software Technology and Theoretical Computer Science. These conferences are organized and run by the computer science research community in India, and their purpose is to provide a forum for professional interaction between members of this research community and their counterparts in different parts of the world. The volume includes four invited papers on: - reasoning about linear constraints using parametric queries, - the parallel evaluation of classes of circuits, - a theory of commonsense visual reasoning, - natural language processing, complexity theory and logic. The 26 submitted papers are organized into sections on logic, automata and formal languages, theory of programming, parallel algorithms, geometric algorithms, concurrency, distributed computing, and semantics.
