IntelligenceIntelligenceIntelligence means intellect, understanding. Intellect is a faculty or reasoning, knowledge, and thinking (Source, Oxford Dictionary)

Intelligence is the computational part of the ability to achieve goals in the world. Varying kinds and degrees of intelligence occur in people, many animals and some machines. (Source, McCarthy, J. 2007, What is artificial intelligence? www-formal.stanford.edu/jmc/whatisai/whatisai.html)

Artificial Intelligence: the art of making computers that behave like the ones in movies

Expert SystemsExpert SystemsExpert Systems are knowledge-based systems that provide

expertise, similar to that of experts in a restricted application area. (Source, Kasabov, Nikola K. 1998, Foundations of Neural Networks,

Fuzzy Systems and Knowledge Engineering, MIT Press).

The neural network, by its simulating a biological neural network, is a novel computer architecture and a novel algorithmization architecture relative to conventional

computers. It allows using very simple computational operations (additions, multiplication and fundamental logic elements) to solve complex, mathematically ill-

defined problems, nonlinear problems or stochastic problems. (Source: Graupe, Daniel, 2007, Principles of Artificial Neural Networks, 2nd Edition, World Scientific).

Rule Based Approach

Fuzzy Inference Systems are systems formulating the mapping from a given input to an output using fuzzy logic (Source, MATLAB

Guide).

Optimizing Agents

Evolutionary Algorithms are algorithms that maintain a population of structures that evolve according to the rules of selection and other

operators, such as recombination and mutation. Each individual in the population is evaluated, receiving a measure of its fitness in the

environment (Source, Spears, William M. 2000, Evolutionary Algorithms, Springer)
