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 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.
