Quand utiliser Lagrange ?
En économie, le multiplicateur de Lagrange permet de déterminer une situation optimale (par exemple comment maximiser son profit, minimiser ses dépenses, ou encore maximiser bien-être) sous une contrainte quelconque (budget limité, bien-être minimum requis).
Pour ecrire le Lagrangien, il faut bien prendre soin de transformer la contrainte sous la forme g(x, y) ≥ 0 et alors le Lagrangien est L = f + λg. Dans le premier cas, il faut réécrire la contrainte R − p1x1 − p2x2 ≥ 0. Le Lagrangien est alors L = U(x1,x2) + λ (R − p1x1 − p2x2).
