SCS Simulation: Special issue on software tools, techniques and architectures for computer simulation

Welcome to this special issue of Simulation: Transactions of the Society for Modeling and Simulation International, which is dedicated to software tools, techniques and architectures for computer simulation. The theme for this issue originated from the core areas of SIMUTools, a young conference organized by the Institute for Computer Sciences, Social Informatics, and Telecommunications Engineering (ICST). In its first three editions, from 2008 to 2010, SIMUTools attracted an energetic community of scientists and practitioners from academia and industry. If you haven’t yet attended the conference or its several colocated workshops, we encourage you to join as a submitting author or participant. Some of the articles in this issue are extended versions of the bestrated publications from SIMUTools 2009, in Rome, Italy, which we had the privilege of serving as program chairs.
