An Overview on Soft Computing Techniques

Soft computing is a term applied to a field within computer science which is characterized by the use of inexact solutions to computationally-hard tasks such as the solution of NP-complete problems, for which an exact solution cannot be derived in polynomial time. This paper explains about the soft computing and its components briefly, also explains the need use and efficiency of its components. 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.
