What I always end up doing is adding print statements or logging between parts of code where data changes until I can eventually isolate the problem to a line or function. It is helpful to manually know what to expect your data to look like at a given step and verify if that is in fact what it is like.

If my algorithm goes awry, the most important method which I believe is dry run using pen and paper. If it works fine but bug still exists then execute it for very simple and easy input and add some display statements in each module as "in module X". If this works. then gradually increase to boundary case inputs and find the illogical code which had made you stuck in debugging nightmare.

1. Reproduce the Bug: Ensure you can consistently reproduce the error with specific inputs. Isolate the problem to simplify debugging. 2. Understand the Algorithm: Revisit the logic of the algorithm step-by-step. Break it down and ensure you fully understand its expected behavior. 3. Add Debugging Statements: Insert print statements or use debugging tools to trace variable values, loop iterations, and decision branches. This helps pinpoint where the issue occurs. 4. Check Edge Cases: Test with edge cases and boundary inputs that might expose flaws in the logic (e.g., empty inputs, maximum constraints). 5. Simplify the Code: Temporarily remove unnecessary parts of the code to focus on the core logic. Simplifying helps isolate the bug.

Sit down and ensure the code is consistently and correctly formatted according to whatever coding standard is in place. This will allow for a far easier visual check. Once this is complete, if the issue still isn't clear, start by setting breakpoints (conditional if helpful) at key points in order to drop into the code and check the current state of all the variables at key stages. This should enable the identification of when the issue is caused. Then you can work through that piece of code, following the algorithm, to figure out what's gone wrong.

One thing I find helpful when debugging an algorithm is to work through it manually on paper. If I can't work through it by hand, then I don't understand it enough to fix it. Once I have worked it out by hand, it can be much easier to follow the same steps I have taken manually through the algorithm itself and test each component individually.

Hi, My approach is simple: I head to a place like A2B, Madurai Idly, or Starbucks to enjoy an amazing cup of filter coffee or French Press. Then, I let my mind wander over the issue at hand—no paper, no pen, no computer—just focused contemplation. This process allows our neural networks to shift to a new optimal solution, facilitating progress in debugging algorithms. The key lies in ensuring that the energy levels of neurons are high enough to learn new information during the debugging process. When energy levels are low, the neurons tend to cycle around equilibrium points, making it difficult to break free and discover new solutions. Best Regards, jk
