(1) Dijkstra algorithm. Dijkstra's algorithm was proposed by Dutch computer scientist Edsger Wybe Dijkstra in 1959, and it has been successfully applied to 2D path planning for mobile robots, computer science,
Dijkstra algorithm is a basic but very interesting subject, and many people would love to create wonderful problems based on it. However, as shown in this blog, making strong tests against wrong implementations of it requires deep consideration of what can actually be mistaken, and relying on la...
Finding the optimum path represent several solutions to solve shortest path search problems. It allows determining a shorter way to get from one city to another, knowing the road network of a region. Specifically, it calculates shorter paths from a source in an oriented graph weighted by ...

He also identified the 'deadlock problem' (called there 'the problem of the deadly embrace') and proposed an elegant 'Banker's algorithm' that prevents deadlock. The deadlock detection and prevention became perennial research problems in the field of concurrent programming. Several of these ideas...
Although Hipster is graph agnostic, we include some useful classes to create a graph or a directed graph and the search problem. We create a graph using the GraphBuilder class and then we use the GraphSearchProblem to create the required components to solve it using Dijkstra's algorithm: ...

The adoption of Osmotic Computing is challenging, but addressing networking issues is a key research topic due to the emergence of new problems in terms of QoS requirements. In this paper, we analyze how to exploit well-known networking solutions, such as the Dijkstra's algorithm, and Big ...
