Feasible Region

The feasible region is the set of all possible solutions that satisfy a problem's constraints, such as limits or conditions. In optimization problems, like maximizing profit or minimizing cost, this region includes every point that meets all the requirements. Think of it as the allowed area on a map where all considered options are valid. Identifying this region helps you focus on solutions that adhere to real-world limitations, enabling you to find the best solution within that safe, permissible zone.
