Question

Suppose to have a linear programming problem. It is known from the optimal solution that allowable increase of the cost coefficient c1 is equal to 20. Initial value of c1 is 50.

Choose the correct statement:

a) If we change the initial value of c1 to 80 nothing will happen

b) If we change the initial value of c1 to 80 the optimal basis will change

c) If we change the initial value of
