Posted by Prabhat Ranjan. Posted In : Genetic Algorithm

Soft computing differs from conventional (hard) computing in that, unlike hard computing, it is tolerant of imprecision, uncertainty, partial truth, and approximation. In effect, the role model for soft computing is the human mind. The guiding principle of soft computing is: Exploit the tolerance for imprecision, uncertainty, partial truth, and approximation to achieve tractability, robustness and low solution cost. The basic ideas underlying soft computi...

General Problem Solving Approaches in AI

To understand what exactly artificial intelligence is, we illustrate some common problems. Problems dealt with in artificial intelligence generally use a common term called 'state'. A state represents a status of the solution at a given step of the problem solving procedure. The solution of a problem, thus, is a collection of the problem states. The problem solving procedure applies an operator to a state to get the next state. Then it applies another o...

History of Artificial Intelligence

January 14, 2011

Professor Peter Jackson of the University of Edinburgh classified the artificial intelligence history into three periods namely

The classical period (of game playing and theorem proving)
The romantic period
The modern period; the major research work carried out during these periods is presented below.

The classical period

This period dates back to 1950. The main research works carried out during this period include game playing and theorem proving. The concept of state-space approach for solving a...

Artificial Intelligence

January 10, 2011

Artificial intelligence (AI) is the intelligence of machines and the branch of computer science that aims to create it. AI textbooks define the field as "the study and design of intelligent agent"where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success.John MaCarthy, who coined the term in 1956, defines it as "the science and engineering of making intelligent machines".

The field was founded on the claim that a central propert...
