Calculate The Optimality Gap With Upper And Lower Bounds

Expert Guide to Calculating the Optimality Gap

Module A: Introduction & Importance

Calculating the optimality gap with upper and lower bounds is crucial in operations research and decision-making processes. It helps evaluate the efficiency of a solution by comparing it with the best possible outcome.

Module B: How to Use This Calculator

1. Enter the upper and lower bounds in the respective fields.
2. Click the ‘Calculate’ button.
3. View the results below the calculator.

Module C: Formula & Methodology

The optimality gap is calculated as:

Gap = (Upper Bound - Lower Bound) / Lower Bound

Where:

• Upper Bound is the best known upper bound of the optimal value.
• Lower Bound is the best known lower bound of the optimal value.
