| Outline of Final Research Achievements |
Many real-world problems can be formulated as combinatorial optimization problems. Although most of them are know to be NP-hard, there exist many algorithms that obtain good quality solutions in reasonable computation time. However, most of such optimization methods are based on the assumption that input data are known a priori and are fixed. On the other hand, input data are often ambiguous and uncertain. We developed several exact and heuristic algorithms to obtain solutions that are robust to such uncertainty, for a representative combinatorial optimization problem called the 0-1 knapsack problem, and we confirmed that the proposed algorithms output good solutions in reasonable computation time.
