Educational diagram illustrating feasible and infeasible regions with feasibility and optimality cuts.

Create a clean, educational diagram showing a polygon (master feasible region). A red shaded area inside it represents infeasible solutions. A straight line cuts off that red area. Label the line with 'Feasibility Cut: removes impossible solutions' and 'Optimality Cut: tightens cost approximation'. Use a simple schematic, clear labels, and textbook-style layout." See more
