Tutorial 7: Degeneracy in linear programming
Degeneracy and Basic Feasible Solutions • We may think that every two distinct bases lead to two different solutions This would be true if there was no degeneracy But with degeneracy we can have two different bases and the same feasible solution We now pivot on the “ 2 ” in Constraint 2 and obtain a second tableau x1-3 3 1 0 -1 |
What is a feasible solution if a matrix is linearly independent?
3. A feasible solution is basic if-and-only-if the columns of the matrix are linearly independent, where K is the set of indices of the non-zero elements of . : 45 4. Each basis determines a unique BFS: for each basis B of m indices, there is at most one BFS with basis B.
