Shown below is pseudocode for Dijkstra’s algorithm. The input is a directed graph G = (V,E) with nonnegative edge weights wt(u, v) for every edge (u, v) ∈ E, and a distinguished node s, called the source (or start) node. The algorithm computes, for each node u ∈ V , the weight of a shortest path from s to u. (It can be easily modified to compute, for each node u, the predecessor of u in a short...

Abstract Determination of the best path or often called shortest finding is a method that has many benefits and can be applied in various cases fields science. In previous studies, authors have developed program using algorithms, such as held-karp, iterative deepening search, bidirectional depth first search limited search. this research author implements on information system for determining f...

We present a parallel priority data structure that im proves the running time of certain algorithms for prob lems that lack a fast and work e cient parallel solu tion As a main application we give a parallel imple mentation of Dijkstra s algorithm which runs in O n time while performing O m log n work on a CREW PRAM This is a logarithmic factor improvement for the running time compared with pre...

Autonomous Mobile Robots (AMRs) are frequently used in many fields of technology. In this study, an AMR was designed to execute different path planning algorithms. Firstly, working principle, system architecture and motion presented. Then, a map for the current environment is produced by Robot Operating System (ROS) powered which study. The locates itself on with aid integrated Light Detection ...

We develop a model for predicting verb sense from subcategorization information and integrate it into SSI-Dijkstra, a wide-coverage knowledge-based WSD algorithm. Adding syntactic knowledge in this way should correct the current poor performance of WSD systems on verbs. This paper also presents, for the first time, an evaluation of SSI-Dijkstra on a standard data set which enables a comparison ...

We revisit a concept that has been central in some early stages of computer science, that of structured programming: a set of rules that an algorithm must follow in order to acquire a structure that is desirable in many aspects. While much has been written about structured programming, an important issue has been left unanswered: given an arbitrary, compiled program, describe an algorithm to de...

The Hoare state monad provides a powerful means of structuring the verification of higher-order, stateful programs. This paper defines a new variant of the Hoare state monad, which, rather than being a triple of a pre-condition, a return type, and a post-condition, is a pair of a return type and a predicate transformer. We dub this monad the Dijkstra state monad. Using the Dijkstra state monad,...
