Bidirectional Dijkstra’s Algorithm is Instance-Optimal

open access: yes
Fixed a bug in the bidirectional search pseudocode where e_mid was updated even if $\mu$ wasn't. Fixed a typo in the proof of Theorem 3: changed all $v_1u_2$ to $u_2v_1$.

How to see the forest despite the trees

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract One of the major starting points of discrete optimization is the theorem of Nash‐Williams and Tutte on the existence of k$k$ disjoint spanning trees of a graph, along with its counterpart on the existence of k$k$ forests covering all edges of the graph.

Least‐Resistance Path as a Proxy for Efficient Simulation of Solute Transport in Heterogeneous Porous Media

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Accurately predicting solute transport remains a central challenge in hydrogeology due to limited data and multiscale subsurface heterogeneity. Fractional Brownian motion (fBm) is widely used to model the logarithm of hydraulic conductivity fields.

A Coalgebraic Dijkstra Algorithm

open access: yes
The Dijkstra algorithm is a classical method for solving the shortest path problem on weighted graphs. There are several variations of the Dijkstra algorithm, including algorithms for the widest path problem and for two-player games. In this paper, we introduce the coalgebraic shortest path problem (CSPP), a unifying framework for a broad class of ...

Intelligent vehicle scheduling in open-pit mines based on 5G antenna and improved Dijkstra algorithm

open access: yesGong-kuang zidonghua
Complex terrains such as deep pits and high slopes in open-pit mines cause physical signal blockage and multipath fading. Furthermore, existing path-planning algorithms tend to result in unstable vehicle trajectories or congestion due to local optima ...

PENCARIAN RUTE TERPENDEK DALAM DUNIA 3 DIMENSI BERDASARKAN ALGORITMA DIJKSTRA

open access: yesJUTI: Jurnal Ilmiah Teknologi Informasi, 2008
Virtual reality is one of the favorite application that very liked by peoples. Vitual reality also used in many games application in order to show the imitation of real world. Recently, virtual reality still imperfect due to shortest path problem.

Finding the Nearest Blood Donors using Dijkstra Algorithm

open access: yesSISFORMA, 2019
Now-a-days frequent mishaps like the road accident or other life-risking accident leading to operational emergencies are increasing day by day and the blood donor for such victims or patients are very hard to find in a short period.
