👉 In mathematics, a variational problem is a type of mathematical problem that seeks to minimize or maximize some function by using an approximation method. The goal of a variational problem is to find a function f that minimizes (or maximizes) a functional F, subject to some constraints on the input variables x and their derivatives dx/dt. The term "variational" refers to the fact that the process of finding such functions involves seeking solutions that depend on certain parameters. This dependence can be thought
