Copyright © 2012 Pearson Education, Inc. 0-2 What is critical thinking? Q: What is the difference between a heuristic and algorithmic solution to a problem? The difference on algorithmic and heuristic solution is that algorithmic requires series of action, and heuristic is built on knowledge and experience
