The second "algorithm" is good in that you _can_ overlook those three things in solving a problem. Defining the problem can be a task in itself. So write it down. Think hard. If you aren't willing to sweat and endure mental pain, then it isn't a problem. It's an exercise. Write it down. Here is where the biggest gap lies in the algorithm. Usually a solution in your head isn't a solution and writing will reveal that. So there is a feedback loop between thinking and writing. All of these are good, but obviously they don't help much beyond the obvious. It probably advantaged Feynman to create a mystique around his problem solving tactics. Which is why it is probably so obvious.
