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...
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, geographic information science, and transportation (Wei et al., 2019; Alyasin et al., 2019; Yu & Ge, 2017...

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: ...
Generalization refers to general language constructs, dynamic (run-time) solutions, and machine-independent language design --in the interest of correctness and reliability. The dichotomy becomes effective if we keep in mind, throughout the sequel, that most ALGOL60 researchers were neither completely...
