Non-crossing Rectilinear Shortest Minimum Bend Paths in the Presence of Rectilinear Obstacles

open access: yesJournal of Telecommunications and Information Technology, 2018
The paper presents a new algorithm to determine the shortest, non-crossing, rectilinear paths in a twodimensional grid graph. The shortest paths are determined in a manner ensuring that they do not cross each other and bypass any obstacles present. Such

A Comparative Study of Single-Constraint Routing in Wireless Mesh Networks Using Different Dynamic Programming Algorithms

open access: yesJournal of Engineering, 2023
Finding the shortest route in wireless mesh networks is an important aspect. Many techniques are used to solve this problem like dynamic programming, evolutionary algorithms, weighted-sum techniques, and others. In this paper, we use dynamic programming

A threshold for majority in the context of aggregating partial order relations [PDF]

open access: yes, 2010
We consider a voting problem where voters have expressed their preferences on a single set of objects. These preferences take the shape of strict partial order relations.

Modifications of the Floyd-Warshall algorithm with nearly quadratic expected-time

open access: yesArs Mathematica Contemporanea, 2021
Summary: The paper describes two relatively simple modifications of the well-known Floyd-Warshall algorithm for computing all-pairs shortest paths. A fundamental difference of both modifications in comparison to the Floyd-Warshall algorithm is that the relaxation is done in a smart way.

Three-Layer Energy Optimization Strategy for CHP Microgrid Considering Path Loss

open access: yesZhongguo dianli, 2023
In order to reduce the dependence of the microgrid on the external system and the operating cost of the microgrid itself, a three-layer energy optimization strategy is proposed for the combined heat and power microgrid cluster.
