Algorithm Design and Analysis

AI Summary: This issue aims to resolve a code scanning alert by auditing URL handling to restrict `url open` calls to only permitted schemes. The goal is to prevent the unexpected and potentially insecure use of `file:/` or custom schemes, ensuring that only approved protocols like HTTP/HTTPS are processed.

Algorithm Design and Analysis

AI Summary: Optimize the Python code snippet `((bifurcationZulu >> 2) << 1)` for CPU performance. The code is part of a larger project focused on map folding algorithms and involves bitwise operations. The optimization should consider different integer bitwidths and explore equivalent expressions like `((n >> 2) * 2)` or `((n >> 1) & 0b11111110)`, aiming for improved efficiency.
