Challenge Problems
Push your limits with challenges.
Question 1
Given five matrices M1 (10x20), M2 (20x30), M3 (30x10), M4 (10x5), and M5 (5x40), determine the optimal order for multiplication to minimize computation, detailing your approach.
💡 Hint: Build a cost table using dimensions to track minimal multiplication costs.
Question 2
Explain how different orders (left-to-right vs right-to-left) in matrix multiplication impact computational cost, using Fibonacci or large matrices as examples.
💡 Hint: Consider the size of intermediate products when choosing multiply orders.
