CHAPTER 2
LINEAR PROGRAMMING – GRAPHICAL METHOD
Graphical Method is used for solving linear programming problems that involve only two variables.
CLOSED HALF PLANE
A linear inequality in two variables is known as a half plane. The corresponding equality or the line is known as the boundary of the half plane. The half plane along with its boundary is called a closed half plane. Thus, a closed half plane is a linear inequality in two variables which include the value of the variable for which equality is attained.
FEASIBLE SOLUTION
Any non-negative solution which satisfies all the constraints is known as a feasible solution of the problem.
FEASIBLE REGION
The collection of all feasible solutions is known as a feasible region.
