FUZZY LOGIC & FUZZY SYSTEMS<br />

BACKGROUND & DEFINITIONS<br />

So why can’t the computers do<br />

what we want the computers to<br />

do?<br />

The solution for some is soft<br />

computing – where methods <strong>and</strong><br />

techniques developed in branches<br />

of computing that deal with<br />

partial information, uncertainty<br />

<strong>and</strong> imprecision<br />

FUZZY LOGIC & FUZZY SYSTEMS<br />

BACKGROUND & DEFINITIONS<br />

“Soft computing differs from conventional<br />

(hard) computing in that, unlike hard<br />

computing, it is tolerant of imprecision,<br />

uncertainty, partial truth, <strong>and</strong> approximation.<br />

In effect, the role model for soft computing is<br />

the human mind. The guiding principle of soft<br />

computing is: Exploit the tolerance for<br />

imprecision, uncertainty, partial truth, <strong>and</strong><br />

approximation to achieve tractability,<br />

robustness <strong>and</strong> low solution cost.”<br />
