Question
If the constraints in a linear programming problem are changed
  1. the problem is to be re-evaluated
  2. solution is not defined
  3. the objective function has to be modified
  4. the change in constraints is ignored

Answer

  1. the problem is to be re-evaluated

Solution:

The optimisation of the objective function of a LPP is governed by the constraints.

Therefore, if the constraints in a linear programming problem are changed, then the problem needs to be re-evaluated.
