When and Why to Recompute Values

Recomputing is the process of re-calculating or re-computing a value that has already been computed and stored, instead of using the previously computed value. This can be done for various reasons such as:

1. To update the value with new information: If new data becomes available, it may be necessary to recompute the value to reflect the updated information.
2. To correct errors: If an error is discovered in the previous computation, it may be necessary to recompute the value to correct the mistake.
3. To improve accuracy: As new methods or algorithms become available, it may be beneficial to recompute values using these new techniques to improve accuracy.
4. To satisfy changing requirements: As the needs of a project or application change, it may be necessary to recompute values to ensure that they meet the new requirements.

Recomputing can be done manually or automatically, depending on the context and the reasons for doing so. In some cases, recomputing may be done periodically as part of a maintenance schedule, while in other cases it may be done on demand in response to specific events or requests.
