How to Use

Using the Lipschitz Constant Calculator is straightforward:

1. Input Maximum Function Difference: Enter the maximum absolute difference between the function values.
2. Enter Maximum Input Difference: Input the maximum absolute difference between the input values.
3. Calculate: Click the “Calculate” button to determine the Lipschitz constant.
4. Result: The calculator will display the Lipschitz constant, indicating the function’s sensitivity to input changes.

Example:

If you have a function with an absolute difference of 5 between two outputs and an absolute difference of 2 between the corresponding inputs, you can use the calculator to determine the Lipschitz constant, which would be 2.5. This value indicates how the function changes in response to changes in the input.
