Study Notes
Module 7 Overview
- Module 7 focuses on advanced topics in Linear Programming (LP), including the use of surplus and artificial variables, Karmarkar's Algorithm, sensitivity analysis, and the dual problem.
Surplus and Artificial Variables
- Surplus and artificial variables are used to convert LP constraints into equalities, enabling the application of the simplex method.
- Surplus variables represent excess capacity, while artificial variables are used to convert inequalities into equalities.
Karmarkar's Algorithm
- Karmarkar's Algorithm is an interior-point method for solving LP problems.
- It is significant because it provides an alternative to the simplex method and has been shown to be more efficient in certain cases.
Sensitivity Analysis
- Sensitivity analysis with the simplex tableau involves analyzing how changes to the LP problem's coefficients affect the optimal solution.
- It involves recalculating the optimal solution after making changes to the problem's data.
The Dual Problem
- The dual problem in LP is a related problem that provides additional insights into the original LP problem.
- The dual problem involves finding the best possible prices for the resources used in the original problem.
- The dual problem is used to identify the shadow prices of the resources, which indicate the change in the optimal value of the objective function when the availability of a resource is increased by one unit.
Recognizing Special Cases
- Recognizing special cases in LP, such as infeasibility, unboundedness, and degeneracy, is important because they can affect the solvability of the problem.
- Infeasibility occurs when there is no feasible solution, while unboundedness occurs when the objective function can be made arbitrarily large.
- Degeneracy occurs when there are multiple optimal solutions, making it difficult to identify a single optimal solution.
