Binary Search Debugging

Efficiently narrowing problem scope through bisection.

Context

You are using binary search to isolate a failure. Works for bugs and regressions.

Domain Context

• Git Bisect: Half the commits; does bug exist here? Repeat until you find the culprit commit
• Code Path: Disable half the code; does bug reproduce? Narrow to affected code
• Data Range: Bugs with specific input; binary search the input space
• Time Range: Regression over time; binary search commits
