WebSep 1, 2024 · Successively, Wu (2007) derived the Karush-Kuhn-Tucker (KKT) conditions of an optimization problem with interval-valued objective function. In this connection, he, using Ishibuchi and Tanaka (1990) partial interval order relations, introduced two different optimization techniques.

Websuch that (x; ) satisfy the gradient KKT conditions. Proof. As before, let I= fi: g i(x) = 0g. We want to express rf(x) as a linear combination of the vectors frg i(x) : i2Ig: that’s what conditions 1 and 3 of the gradient KKT theorem promise us. (Condition 1 says rf(x) is a linear combination of all the gradients; condition 3 says that the ...
