subsubproblem

Noun

1. A subproblem of a subproblem.
   • 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"...
   • In contrast, dynamic programming applies when the subproblems overlap—that is, when subproblems share subsubproblems. - 2009, Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, Introduction to Algorithms, page...
