For LC2386, if the restriction of k (<= 2000) is removed, then unless P=NP, this problem cannot be solved in P. We can reduce the subset sum problem to it. If LC2386 has an algorithm in P, the subset sum problem could be solved in P using binary search queries. For example the...
example,Fink et al. (2019)applied Dijkstra's algorithm to a planetary rover in a 3D environment,Balado et al. (2019)applied Dijkstra's algorithm in combination with point cloud maps for path planning in urban 3D environments, andYu et al. (2018)introduced Dijkstra's algorithm in the field...
In order to make dijkstra work in this problem, you would have to visit every node again if the distance got updated, making the algorithm run in O(m2logn)O(m2logn). This is the same reason as to why dijkstra doesn't work with negative weights. Instead of dijkstra, this problem ...

As it turns out, while the algorithm you (I imagine) intended to implement isO(n^4), your code was actuallyO(n^2)all along. If this really resulted in TLE, Python is not going to be able to handle this question. What I find much more likely is that your code failed due to ...
The weights of arcs can be expressed with bipolar neutrosophic numbers based on positive and negative effects and the fuzzy graph can be solved with the Dijkstra algorithm for the shortest path problem. This study shows how the Dijkstra algorithm is used to find the shortest path of arcs ...
Answer to: Give an example where Dijkstra's algorithm gives the wrong answer in the presence of a negative edge but no negative cost cycle. By...
This allowed him to present the more than 2300 years old Euclid's algorithm for computing the greatest common divisor of two natural numbers in an aesthetically pleasing symmetric form. Since then the concept of a guard spread deeply inside computer science. In 1976 he published a seminal book,...
(2018) solved the two-way route planning model by using Dijkstra algorithm. Sun et al. (2020) converted failure probability into risk entropy to represent the weight of arc. The Dijkstra algorithm was employed to find the shortest path of accident escalation. Feng et al. (2020) used the ...
