We also discover that the running time of the Generic Dijkstra algorithm in the function of network utilization is not monotonic, as peak running time is at approximately 0.25 network utilization. Additionally, we provide an independent open source implementation of Generic Dijkstra in the Python ...
For example, if we say that an algorithm has a time complexity of O(n), it means that the algorithm’s execution time increases linearly with the size of the input. If the input size doubles, the time it takes to run the algorithm will roughly double as well. If an algorithm is O(...
Welp, life is full of trade-offs. One way or another we took a course to fight accidental complexity, so we can deliver faster and more, so we can solve bigger and bigger problems. Today we rarely write an algorithm instead we take something ready from the shelf, we rarely implement ...

The application of Dijkstra’s algorithm on the considered instance, is presented in Fig. 3. To be more clear, the best solution for this instance is to turn the machine on from time-slot 0 and process all the jobs based on their order during time-slots 3 to 7, and finally, turning ...

simply maximizing the number of placed labels, as often done for labeling point features, can cause undesired effects like unnamed roads or clumsy label placements (e.g., the unlabeledDijkstra St.and the threefold labeledHamming St.in Fig.1a. In order to overcome the problems outlined, we aim...

We show that Directed Multiplicative Spanner admits a kernel of size O(k4t5). We complement this result by observing that the problem can be solved in (4t)k · nO(1) time by a Monte Carlo algorithm with false negatives. We leave open the question whether the prob- lem is FPT when ...
