Question

Define degeneracy in simplex method in operation research

Answer 1

Answer:

DEGENERACY. ... In other words, under Simplex Method, degeneracy occurs, where there is a tie for the minimum positive replacement ratio for selecting outgoing variable. In this case, the choice for selecting outgoing variable may be made arbitrarily.

What is replacement ratio in simplex method? - Brainly.in

koSimplex method or Dantzig's simplex

algorithm is a popular algorithm for linear programming in mathematical

optimization. The name was suggested by T.S. Motzkin and is derived from the

concept of a simplex.

Two variable LP models can be

solved using the graphical method. But it is not applicable for three, four or

five variable problems. The simplex method is an iterative method that gives

the solution to any n variable LP model by repeated use.

The solution is arrived at by

replacing the variables. The variable which is replaced is known as the leaving

variable and the variable which replaces is called the entering variable. The

simplex method is designed in such a way that two things happen during the

process of choosing the variables. The new value is an improvement on the

current one and the new solution is feasible.
