This volume contains the proceedings of AMAST 2004, the 10th International Conference on Algebraic Methodology and Software Technology, held during July 12-16,2004,in Stirling, Scotland, UK. The major goalof the AMAST c- ferences is to promote research that may lead to the setting of software techn- ogy on a ?rm, mathematical basis. This goal is achieved by a large international cooperationwith contributions from both academia and industry. The virtues of a software technology developed on a mathematical basis have been envisioned asbeing capableofprovidingsoftwarethatis(a)correct,andthecorrectnesscan be provedmathematically, (b) safe, so that it can be used in the implementation of critical systems, (c) portable, i. e. , independent of computing platforms and language generations, and (d) evolutionary, i. e. , it is self-adaptable and evolves with the problem domain. PreviousAMASTmeetingswereheldinIowaCity(1989,1991,2000),Twente (1993), Montreal (1995), Munich (1996), Sydney (1997), Manaus (1999), and Reunion Island (2002), and contributed to the AMAST goals by reporting and disseminating academic and industrial achievements within the AMAST area of interest.During these meetings, AMAST attracted an international following among researchersand practitioners interested in software technology, progr- ming methodology and their algebraic and logical foundations. For AMAST 2004therewere63 submissionsof overallhigh quality, authored by researchers from Australia, Canada, China, the Czech Republic, Denmark, France, Germany, India, Iran, Israel, Italy, Korea, Portugal,Spain, Taiwan, The Netherlands, Turkey, the UK, and the USA. All submissions were thoroughly evaluated, and an electronic programcommittee meeting was held to discuss the reviewers' reports. The program committee selected 35 papers to be presented.
