What is Slack and Surplus Variables in LP about?

This document discusses slack and surplus variables in linear programming models. It explains that slack variables are added to inequality constraints to convert them into equations, and represent unused resources. Surplus variables are subtracted from constraints to also convert them into equations, and represent excess above a required level. The document provides examples of linear programming models with slack and surplus variables, and discusses how they do not contribute to the objective function but
