Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a thought experiment where you assume a different problem (other than the Halting Problem) is solvable. Show how proof by contradiction can illustrate its undecidability.

💡 Hint: Similar structures of recursive functions can be employed to reveal contradictions.

Challenge 2 Hard

Reflect on the practical consequences of the Halting Problem’s undecidability on modern computing. Write a brief essay on how this impacts software development.

💡 Hint: Think of recent advancements in AI and how these complexities surface in practice.
