simplex method - linear programming Flashcards
it requires that all constraints be expressed as equations
simplex method
it is an iterative technique that begins with a feasible solution that is not optimal, but serves as a starting point
simplex method
define
standard form:
slack variable:
surplus variable:
artificial variable:
standard form: is the way the problem is expressed mathematically
slack variable: convert “less than or equal to” constraints into equations by adding a non negative variable
surplus variable: convert “greater than or equal to” constraints into equations by subtracting a non-negative variable
artificial variable: temporary variables used to find an initial basic feasible solution when one does not exist naturally (=)
these variables help convert the original problem into a form that can be solved using the simplex method, which is an iterative algorithm for finding the optimal solution to a linear programming problem
it is a table use to keep track of the calculations made when the simplex method is employed.
simplex tableau
right hand side -
basic variables -
right hand side - the column in the simplex tableau indicating the quantities of the variables is in a solution
basic variables - variable include in a basic solution
it is a simplex method which consists of the sequence of steps (row operations) performed in moving one basic feasible solution to another.
