Fundamentals of Computation Theory

This volume contains the proceedings of the Ninth Conferenceon Fundamentalsof Computation Theory (FCT 93) held inSzeged, Hungary, in August 1993. The conference was devotedto a broad range of topics including:- Semanticsand logical concepts in the theory of computingand formal specification- Automata and formal languages- Computational geometry, algorithmic aspects of algebra andalgebraic geometry, cryptography- Complexity (sequential, parallel, distributed computing,structure, lower bounds, complexity of analytical problems,general concepts)- Algorithms (efficient, probabilistic, parallel,sequential, distributed)- Counting and combinatorics in connection with mathematicalcomputer scienceThe volume contains the texts of 8 invitedlectures and 32short communications selected by the international programcommittee from a large number of submitted papers.
