WebbInterestingly enough, it turns out it encapsulates both the MMCC and primal network simplex algorithms as extreme cases. By guiding the solution using a particular expansion scheme, we are able to recuperate theoretical results from MMCC. As such, we obtain a strongly polynomial Contraction-Expansion algorithm which runs in O(m3n2) time. Webb9 mars 2024 · According to the lower bound theory, for a lower bound L (n) of an algorithm, it is not possible to have any other algorithm (for a common problem) whose time complexity is less than L (n) for random input. Also, every algorithm must take at least L (n) time in the worst case.
