Key Insights

• 👻 Duality is an important concept in linear programming as it allows complex minimization problems to be solved by transforming them into easier maximization problems.
• 💁 The steps to solve a linear programming problem using duality include setting up a linear program in standard minimization form, formulating a dual problem in standard maximization form, using the simplex method to solve the dual maximization problem, and identifying the optimal solution to the original minimization problem from the optimal simplex tableau.
• ❓ Slack variables in the dual problem have the same values as the original decision variables in the primal problem.
• ❓ The coefficients for the decision variables in the primal problem become the slack variables in the dual problem.
