Polylogarithmic time
An algorithm is said to run in polylogarithmic time if its time is for some constant k. Another way to write this is . For example, matrix chain ordering can be solved in polylogarithmic time on a parallel random-access machine, and a graph can be determined to be planar in a fully dynamic way in time per insert/delete operation. Webically in polylogarithmic time in (general) graphs? (2) Is the constant factor in the dynamic algorithms small such that an efficient implementation is possible? New Results. This …

WebJun 9, 2024 · On the other hand, nondeterministic polylogarithmic time complexity classes, defined in terms of alternating random-access Turing machines and related families of circuits, have received some attention [5, 18]. Recently, a theorem analogous to Fagin’s famous theorem , was proven for nondeterministic polylogarithmic time . WebJul 15, 2024 · We present dynamic algorithms with polylogarithmic update time for estimating the size of the maximum matching of a graph undergoing edge insertions and deletions with approximation ratio strictly better than $2$. Specifically, we obtain a $1+\\frac{1}{\\sqrt{2}}+ε\\approx 1.707+ε$ approximation in bipartite graphs and a …
WebAn algorithm is said to have polynomial time complexity if its worst-case running time T worst(n) T worst ( n) for an input of size n n is upper bounded by a polynomial p(n) p ( n) for large enough n≥ n0 n ≥ n 0 .
