In mathematical optimization, the method of Lagrange multipliers is a strategy for finding the local maxima and minima of a function subject to equality constraints (i.e., subject to the condition that one or more equations have to be satisfied exactly by the chosen values of the variables). It is named after the … See more The following is known as the Lagrange multiplier theorem. Let $${\displaystyle \ f\colon \mathbb {R} ^{n}\rightarrow \mathbb {R} \ }$$ be the objective function, See more The method of Lagrange multipliers can be extended to solve problems with multiple constraints using a similar argument. Consider a paraboloid subject to two line constraints … See more In this section, we modify the constraint equations from the form $${\displaystyle g_{i}({\bf {x}})=0}$$ to the form $${\displaystyle \ g_{i}({\bf {x}})=c_{i}\ ,}$$ where the See more Example 1 Suppose we wish to maximize $${\displaystyle \ f(x,y)=x+y\ }$$ subject to the constraint See more For the case of only one constraint and only two choice variables (as exemplified in Figure 1), consider the optimization problem See more The problem of finding the local maxima and minima subject to constraints can be generalized to finding local maxima and minima on a differentiable manifold Single constraint See more Sufficient conditions for a constrained local maximum or minimum can be stated in terms of a sequence of principal minors (determinants of upper-left-justified sub-matrices) of the bordered Hessian matrix of second derivatives of the Lagrangian expression.
