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.

A statement form is satisfiable if there is an assignment True/False for its variables such that the statement form is True. Otherwise, that is, if no such assignment exists, the statement form is called unsatisfiable. Consider the statement form = (p → q) ^ (~ p V r) ^ (qV ~ r) Use a possibility tree to decide if is satisfiable or not.
