The area of Implicit Computational Complexity (ICC) has grown out from several proposals to use logic and formal methods to provide languages for complexity-bounded computation (e.g. Ptime, Logspace computation). It aims at studying computational complexity without referring to external measuring conditions or a particular machine model, but only by considering language restrictions or logical principles implying complexity properties. This workshop focuses on ICC methods related to programs (rather than descriptive methods). In this approach one relates complexity classes to restrictions on programming paradigms (functional programs, lambda calculi, rewriting systems), such as ramified recurrence, weak polymorphic types, linear logic and linear types, and interpretative measures. The two main objectives of this area are: Therefore ICC is related on the one hand to the study of complexity classes, and on the other hand to static program analysis. The workshop will be open to contributions on various aspects of ICC including (but not exclusively): The first two DICE workshops were held in 2010 in Cyprus and in 2011 in Germany, both as part of ETAPS conferences. Before that, several meetings on this topic had already been held with success in Paris (WICC 2008), and Marseille (GEOCAL 2006 workshop on Implicit computational complexity).
