The paper studies the application of convex functions in order to prove the existence of optimal solutions of an overdetermined system of linear
equations. The study approaches the problem by using even convex functions instead of projections. The research also relies on some special
properties of unbounded convex sets, and the lower level sets of continuous functions.
