This book constitutes the refereed proceedings of the 12th Annual Conference on Theory and
Applications of Models of Computation TAMC 2014 held in Singapore in May 2015. The 35
revised full papers presented were carefully reviewed and selected from 78 submissions. The
papers treat all topics relating to the theory and applications of models computation for
example recursion theory and mathematical logic computational complexity and Boolean functions
graphy theory quantum computing parallelism and statistics learning automata and
probabilistic models parameterised complexity.
