Utilizing graphs with unique node labels reduces the complexity of the maximum common subgraph problem, which is generally NP-complete, to that of a polynomial time problem. Calculating the maximum common subgraph is useful for creating a graph distance measure, since we observe that graphs become ...
Iteration over the long sequencing reads, as opposed to an all-vs-all alignment of reads, allows GoldRush to achieve a linear time complexity in the number of reads. We show that GoldRush produces contiguous and correct genome assemblies with a low memory footprint, and does so without read-...
Dijkstra’s and Johnson’s algorithm have a runtime complexity of O(ne + n2log(n)), where n is the number of nodes and e the number of edges. Their main difference is, that Johnson’s algorithm can additionally deal with negative weights by adjusting weights before searching paths with ...

The time complexity of this method is comparable to if not superior to most community detection methods when applied directly to each network snapshot just to find the phase transitions. The time complexity of computing the Forman-RC network entropy for one network snapshot is \({\mathscr {O}...

We have attempted more complicated measures such as MSM [52] and TWED [31]. They are very time-consuming because they have at least quadratic time complexity, and neither of them (using the Python implementations from sktime [30]) could complete the run within the 2-day time frame for an...

The original complexity–entropy plane The first example of a complexity–entropy plane was proposed by O. Rosso and co-authors71. Time series are characterised by two values, which are used to position them in a bi-dimensional plane. The first one is the classical permutation entropy, normalis...
