Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Calculate the time complexity if the length of the string is 8, and the grammar has 15 production rules. Explain each step in your calculation.

💡 Hint: Focus on the relationships of the nested loops.

Challenge 2 Hard

Discuss the implications of changing the grammar size to 50 production rules. What impact does it have on the CYK algorithm's performance?

💡 Hint: Consider how large grammar sizes influence nested loop computations.
