Toward Optimization of AGV Path Planning: An RRT^*-ACO Algorithm

IEEE Access
Automated guided vehicle (AGV) smart parking provides a new solution to solve the problem of urban parking difficulties. In the AGV parking lot, whether the AGV running path is reasonable affects the transportation efficiency of the entire parking lot ...

Ant Colony Optimization Algorithm

Journal of Applied Technology and Innovation
ACO is a potent algorithm inspired by ants' social behavior. It can solve complex computational problems and offers a promising approach to finding near-optimal solutions in various domains. This essay focuses on ACO's potential to solve the Travelling Salesman Problem (TSP) by mimicking ants' pheromone-based path finding.

Behavioral, Ecological, and Morphological Data Suggest a Close Relationship Between the Ant Colobopsis truncata and the Gall Wasp Aphelonyx cerricola

Integrative Zoology, EarlyView.
Aphelonyx cerricola and the different stages that make this gall colonizable by ants. ABSTRACT Wasps of the family Cynipidae are known to induce galls of a species‐specific morphology, which during senescence provide a refuge for secondary insect fauna, especially ants.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Contrastive ecoacoustic indices: Large‐scale global soundscape characterization with contrastive inference

Methods in Ecology and Evolution, EarlyView.
Abstract Ecoacoustics mainly aims at monitoring soundscapes by means of non‐invasive protocols. Despite the widespread adoption of machine and deep learning techniques, existing ecoacoustic models predominantly rely on supervised learning and, consequently, face two primary limitations: (1) the necessity of annotated data; and (2) the restriction to ...

Controllable Intrinsic Surface Pattern Generation Using Slime Mold Simulations

Computer Graphics Forum, EarlyView.
Abstract Surface‐based pattern simulations have proven valuable for texture design and scientific visualization, but existing methods face several limitations. Most simulations either target a narrow range of pattern types (e.g. spots, branching) or support a broad range of patterns at the cost of time‐consuming parameter tuning.

Sheep and cattle grazing regimes differentially affect ground beetle and ant communities in Mediterranean cork oak woodlands

Insect Conservation and Diversity, EarlyView.
Sheep and cattle grazing significantly shape ant and ground beetle species composition in Mediterranean cork oak woodlands, promoting higher diversity by increasing habitat heterogeneity. Ground beetles and ants reflect changes in grazing regimes, with sheep‐grazed areas showing the highest diversity, highlighting their utility in ecosystem monitoring.

Forest disturbance and the spread of invasive species disrupt diel activity patterns in New Guinea ant communities

Insect Conservation and Diversity, EarlyView.
Primary forests hosted more diurnal species and exhibited significant diel specialization. Secondary forests were less species‐rich, dominated by invasive ants, with reduced diel partitioning and more species active at night. Although the overall ant activity was higher during the day, this pattern was stratum‐dependent: arboreal and terrestrial ants ...

Collaborative platooning and routing for mixed fleets of electric automated vehicles and conventional trucks

International Transactions in Operational Research, EarlyView.
Abstract The application of automated ground vehicles (AGVs) is well‐established in closed environments such as port terminals, while their operation in open areas remains challenging. In this work, we set out to overcome this limitation by introducing platooning as a transfer mode in heterogeneous vehicle networks.

A TSP Solving Model Based on Immune Ant Colony Hybrid Algorithm

工程科学与技术, 2010
:In order to solve the problems caused by the traditional ant colony algorithm, such as searching slowly, cling to prematurity, standstill, and the inefficient and useless redundant iteration caused by feedback underutilized in traditional immune ...
