Slack variable - Wikipedia, the free encyclopedia
In Linear programming a slack variable is a variable that is added to a constraint to turn the inequality into an equation. This is required to turn an inequality into an equality where a linear com...

Slack variables are used in Linear Optimization to turn constraints stated as inequalities into equalities and a constraint that the slack variable be non-negative. Linear programming problems should be set up so that all variables must be non-negative anyway, so this last constraint isn't so important.

Since we don't know what that quantity is, we give it a variable name, "s-sub something-or-other." (These variables are traditionally named "s" to stand for the "slack" they take up between the "less than" and the "equals.") Next, observe that the function we want to maximize is named "P", and it is an equation,
