<p>to <a href="page.php?w=Optimization_%28mathematics%29">mathematical optimization</a>, <a href="page.php?w=Richard_Bellman">Richard Bellman</a>'s <a href="page.php?w=Bellman_equation">Principle of Optimality</a> is based on the idea that in order to solve a dynamic optimization problem from some starting period t to some ending period T, one implicitly has to solve subproblems starting from later dates s, where t<s<T</i>. This is an example of optimal substructure. The Principle of Optimality is used to derive the <a href="page.php?w=Bellman_equation">Bellman equation</a>, which shows how the value of the problem starting from t is related to the value of the problem starting from s.</s<t</i></p><p>
