subsubproblem

plural subsubproblems

1. A subproblem of a subproblem.

   In contrast, dynamic programming applies when the subproblems overlap—that is, when subproblems share subsubproblems.

   If the subproblems are still too complex to grasp easily, these in turn can be decomposed into subsubproblems. This process of successive problem analysis and decomposition can be illustrated by using a "problem tree" structure.
