Metode Subgradien Pada Fungsi Nonsmooth

Abstract

Nonlinier function with absolut variable is nonsmooth function which the derivative can be solved by Subgradien method. A vector is subgradien from to if ( ) ( ) ( )

( ) If conveks and differentiable , ( ) is subgradien from to . Subgradien from absolut function has different value when the function toward and . Nonlinier function with certain degree variable is affiliation from few segments of nonsmooth function so it looks like smooth function, but in greatest value, that function will revert to nonsmooth function.
