Question

What is replacement ratio in simplex method?

Answer 1

Simplex 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. 

Answer 2

Step-by-step explanation:

Simplex 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.
