The video explores the geometrical interpretation of linear programs, starting with a two-dimensional example. It explains how constraints form a feasible region, represented as a polygon, and how the objective function is minimized within this region. The video then generalizes these concepts to higher dimensions, where feasible regions become polyhedra. The approach provides an intuitive understanding of linear programming and its solutions.
