: Finite computing agents that interact with an environment are shown to be more expressive than Turing machines according to a notion of expressiveness that measures problemsolving ability and is specified by observation equivalence. Sequential interactive models of objects, agents, and embedded systems are shown to be more expressive than algorithms. Multiagent (distributed) models of coordination, collaboration, and true concurrency are shown to be more expressive than sequential models. The technology shift from algorithms to interaction is expressed by a mathematical paradigm shift that extends inductive definition and reasoning methods for finite agents to coinductive methods of set theory and algebra. An introduction to models of interactive computing is followed by an account of mathematical models of sequential interaction in terms of coinductive methods of nonwellfounded set theory, coalgebras, and bisimulation. Models of distributed information flow and multiagent inter...

The notion of computation has attracted researchers from a wide range of areas, cognitive psychology being one of them. The analogy underlying the (metaphorical) usage of "computer" in cognitive psychology can be succinctly summarized by saying that the mind is to the brain as the program is to the hardware. Two main assumptions are buried in this analogy: 1) that the mind can somehow be understood computationally, and 2) that the same kind of relationthe implementation relationthat obtains between programs and computer hardware obtains between minds and brains too. While the first assumption has led to fertile research, the second remained mainly at the level of an assumption. Recently our

1 Introduction to Complexity Theory &quot;Complexity theory &quot; is the body of knowledge concerning fundamental principles of computation. Its beginnings can be traced way back in history to the use of asymptotic complexity and reducibility by the Babylonians. Modern complexity theory is the result of research activities in many different fields: biologists studying models for neuron nets or evolution, electrical engineers developing switching theory as a tool to hardware design, mathematicians working on the foundations of logic and arithmetics, linguists investigating grammars for natural languages, physicists studying the implications of building Quantum computers, and last but not least, computer scientists searching for efficient algorithms for hard problems. The course will give an introduction to some of these areas. In this lecture we introduce the notation and models necessary to follow the rest of the course. First, we introduce some basic notation. Afterwards, we discuss the question &quot;what is computation?&quot;, followed by definitions of various types of Turing machines. We also introduce some basic complexity classes for these machines.
Formalism and intuition in computability

The model of recursive functions in 1934–1936 was a deductive formal system. In 1936, Turing and in 1944, Post introduced more intuitive models of Turing machines and generational systems. When they both died prematurely in 1954, their informal approach was replaced again by the very formal Kleene Tpredicate for another decade. By 1965, researchers could no longer read the papers. A second wave of intuition arose with the book by Rogers and Lachlan’s revealing papers. A third wave of intuition has arisen from 1996 to the present with a return to the original meaning of computability in the sense of Turing and Gödel, and a return of ‘recursive ’ to its original meaning of ‘inductive ’ and the founding of Computability in Europe by Cooper and others.
