We follow the research philosophy of the Feynman algorithm to solve hard problem.

Write down the problem

It reminds us that writing down a precise yet comprehensive problem definition is a key step towards a solution. Often enough, this actually is the most difficult part.

Think hard

The thinking really hard part remains what it is—hard. The good news is: There are some methods and tools to help.

Write down the solution

Finally, We consider step 3 as a reminder that formulating the solution requires at least as much care and attention as the previous steps.
