... Introduction of Theory of Computation Last Updated: 13-05-2020. Applications of Pumping Lemma. Cardinality : Number of elements in a set, which is basically |Σ|n. Theory of computation is the branch that deals with how efficiently problems can be solved on a model of computation, using an algorithm. The main motivation behind developing Automata Theory was to develop methods to describe and analyse the dynamic behavior of discrete systems. The idea that individual molecules (or even atoms) could be used for computation dates to 1959, when American physicist Richard Feynman presented his ideas on nanotechnology.
