Primal Problem - an overview ScienceDirect Topics

WebUnder strong duality, if we are given dual optimal u;v , any primal solution minimizes L(x;u;v ) over all x, because of the stationary condition. This can be used to characterize or compute primal solutions. Explicitly, given a dual solution u;v , any primal solution x solves min x f(x) + Xm i=1 u i@h(x) + Xr j=1 v j @l j(x): 13-1 WebFor any primal problem and its dual problem, all relationships between them must be symmetric because the dual of the dual is primal.

Web4.1.3 The Dual Linear Program Shadow prices solve another linear program, called the dual. In order to distinguish it from the dual, the original linear program of interest – in this case, the one involving decisions on quantities of cars and trucks to build in order to maximize proﬁt – is called the primal. We now formulate the dual. WebMay 4, 2024 · The dual of the dual problem is: minimizexϕ ∗ ∗ (x, 0). But typically we have ϕ ∗ ∗ = ϕ, in which case the dual of the dual problem is exactly the primal problem. You might wonder how this dual problem construction connects to the standard dual problem construction (where you first form the Lagrangian, etc.).
