An artist’s impression of a quantum electrodynamics simulation using 100 qubits of an IBM quantum computer. The spheres and lines denote the qubits and connectivity of the IBM quantum processor; gold ...

The original version of this story appeared in Quanta Magazine. If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle ...

In the Dijkstra algorithm, when a shorter path to a neighbor is found, the neighbor's priority in the priority queue should be updated regardless of whether it is already present in the queue. In this ...

Abstract: Dijkstra algorithm is not improved in terms of space and time-complexity, the algorithm is muddled to apply in network analysis for enormous test cases. To handle this huge time complexity, ...

This project solves the problem of transporting heavy loads between cities by finding viable paths through viaducts with height restrictions, using a modified Dijkstra's algorithm for optimal routing.

Many efforts to apply machine learning get stuck due to concerns about the “black box” — that is, the lack of transparency around why a system does what it does. Sometimes this is because people want ...
