Dynamic programming is a combinatorial optimization technique that transforms overlapping subproblems in backtracking search algorithms into independent instances by reformulating state transitions to solve remaining capacity constraints rather than extending partial solutions. The core mechanism relies on memoization within a two-dimensional table indexed by capacity and item index, ensuring each unique state $(c, i)$ is computed exactly once to reduce time complexity from exponential $O(2^n)$ to pseudo-polynomial $O(nC)$. This approach optimizes recursive backtracking procedures for problems characterized by optimal substructure in the domain of algorithm design.
