Outline of Final Research Achievements

Results on theory of algorithms and computational complexity with exact theoretical guarantees have been obtained, including those below. (1) Relationship among several problems with respect to exponential-time complexity has been revealed, which opened up a new direction in the field. (2) Improvement has been obtained for finding the maximum and the minimum by unreliable comparisons. (3) The labeled token swapping problem has been shown to be NP-complete, 4-approximable for general graphs and 2-approximable for trees.
