[1.3] ============================================= AMAST News, Sample Issue 01 Theoretical Computer Science 140:1 (March 1995) Special Issue AMAST'93 (G. Scollo and T. Rus, guest editors) The papers in this issue are revised and extended versions of communications presented at the Third International Conference on Algebraic Methodology and Software Technology, held on June 21--25, 1993, at the University of Twente, Enschede, The Netherlands. Among the objectives of the conference, were: to consolidate and expand the trend created by the international dialogue established by the previous two AMAST conferences, and to make a new step toward transforming algebraic methodology into software technology. The six papers selected for this issue testify to the successful achievement of the objectives of the conference. The topics they address are diverse; the approaches, problems and results they propose are novel and, though seemingly unconnected, together they yield a coherent enrichment of the potential of using algebraic methods in the science and technology of computing.
