Optimization: Dual and Lagrangian

Dependencies: None

Consider the optimization problem P: minxRdf(x) where iI,ci(x)0jJ,hj(x)=0 The corresponding Lagrangian is L(x,λ,μ)=f(x)λTc(x)μTh(x) Define g as g(λ,μ)=minxRdL(x,λ,μ) Let D be this optimization problem: maxλ,μg(λ,μ) where g(λ,μ)λ0 Then D is said to be the dual of P.
