Solutions to a dynamic programming problem have (at minimum) three things: – A recurrence relation – A brief description of what your recurrence function represents and what each case represents. – A brief description of the memory element/storage and how it’s filled in. – Always give complete solutions, not just examples.– Always declare all your variables, in English. In particular, always describe the specific - problem your algorithm is supposed to solve. – Never use weak induction.
