Define problem constraints.

• Ans 1: The system of linear inequalities involved in the problem concerned is called problem constraints.

State fundamental extreme point theorem.

• Ans 1: From all the points in a plane bounded by a number of lines the maximum or minimum value of the objective function occurs only at one of the vertices of the bounded linear region.

• Ans 1:

• Ans 1:

• Ans 1:

• Ans 1:

• Ans 1:

Define optimal solution

• Ans 1: The feasible solution, which maximizes or minimizes the objective function, is called the optimal solution.

• Ans 1:

• Ans 1:

Define an objective function.

• Ans 1: A function, which is to be maximized or minimized, is called an objective function.

• Ans 1:

What are constraints in linear programming ?

• Ans 1: The conditions in the form of linear equations and in-equations are known as constraints.

Define problem constraints.

• Ans 1: The system of linear inequalities involved in the problem concerned is called problem constraints.

• Ans 1:

• Ans 1:

• Ans 1:

• Ans 1:

• Ans 1:

• Ans 1:

• Ans 1:

Check whether the region of graph 2x + 3y > 1 lies on the origin side or not.

• Ans 1: The graph of 2x + 3y > 1 is an open half plane.
  As 2(0) + 3 (0) > 1 is not true.
  So the region is not on the origin side.

• Ans 1:

Define convex region.

• Ans 1: if the line segment obtained by joining any two points of a region lies entirely within the region, then the region is called convex.

• Ans 1:

• Ans 1:

• Ans 1:
