Foreword This volume contains 12 selected papers of the first workshop on Tools and Algorithms for the Construction and Analysis of Systems, TACAS'95, which took place at the University of Aarhus (Denmark), May 19-20. TA- CAS brought together 46 researchers interested in the development and application of tools and algorithms for specification, verification, analysis and construction of distributed systems. The overall goal of the workshop was to compare the various methods and the degree to which they are supported by interacting or fully automatic tools. During the two days 23 presentations selected from 32 submissions were given, covering a variety of topics including refinement-based and compositional verification, construction techniques, analysis and verification via theorem-proving, process algebras, temporal and modal logics, techniques for real-time, hybrid and probabilistic systems, and approaches for valuepassing systems. In addition special sessions for tool demonstration were held, showing surprising performance even in cases where worst case complexity estimations hardly allowed any optimism. TACAS was hosted by BRICS, the center of the Danish National Research Foundation at the Computer Science Departments of Aarhus and Aalborg Universities, and the local organization was in the hands of Uffe H. Engberg, Kim G. Larsen, Birger Nielsen, and Arne Skou, who were supported by the experienced TAPSOFT'95 organizers Peter D. Mosses and Karen K. Moiler. This combination guaranteed a perfect and enjoyable event. Finally, we would like to thank all the referees who assisted us in the paper selection: L. Aceto, F. Andersen, V. Braun, E.H. Eertink, A.
