Computational Intelligence, Soft Computing, Natural Computation are different names for more or less simular things, namely a couple of mathematical methods, which are geared to mechanisms and procedures of the nature. They are all characterized by an extremely high degree of functionality and robustness. Basically these methods comprise of

Contrary to the classical, strictly formal branch of Artificial Intelligence these methods are more oriented on pragmatic, well functioning solutions and less on theoretical and formal clarity, which is anyway seldomly existend in "real-world applications". Thus most complicated tasks can be solved quickly and efficiently hereby. For a lot of complex problems these methods are often the only practically existing solution strategies.
