The dual problem possesses an extraordinary property: its optimal solution corresponds to the optimal solution of the original problem. This duality is not merely coincidental but rather a profound result of convex analysis, the study of sets that have “nice” curves. Convexity, in this context, ensures that the hills and valleys of the objective function behave in a well-behaved manner, allowing us to effortlessly navigate the optimization landscape.

The practical implications of duality theory are far-reaching. By solving the dual problem, we gain valuable information about the original problem’s structure and optimal solution. For instance, if the dual problem has a finite optimal solution, so does the original problem, giving us assurance of convergence and precision.

The concept of duality arises from the fact that every optimization problem has two sides: the primal problem and its corresponding dual problem. The primal problem seeks to minimize an objective function, while the dual problem aims to maximize a different objective function. Remarkably, the optimal values of these two problems are always equal.

Key to duality theory are concepts such as Lagrange multipliers and convex conjugation. Lagrange multipliers represent the interplay between the primal and dual problems, providing valuable information about the problem’s constraints.
