Summary: In recent decades, numerous algorithms have been proposed to solve optimization problems, some of which are inspired by nature. The collective behavior of ants, which demonstrates intelligence in nature, has served as a source of inspiration for optimization algorithms. Building upon the concept of path integration, this paper presents a new optimization algorithm, Ant Path Integration, by modeling the swarm intelligence of desert ants in finding their return path to the nest.

Summary: This article provides a brief overview of the skills of Cataglyphis desert ants in multisensory learning and neuronal plasticity, focusing on their transition from the dark nest interior to performing first foraging trips. It highlights desert ants as experimental models for studying the neuronal mechanisms underlying behavioral development into successful navigators.

Summary: Wood ants can learn routes using magnetic directional cues, but their performance can be affected by competing directional cues. Additionally, there is evidence that ants develop magnetically directed home and food vectors based on path integration. However, ants perform worse than honeybees in utilizing magnetic information contextually.

Summary: Calaglyphis desert ants calibrate their compass systems and learn visual panoramas at the beginning of foraging careers, using structured initial learning walks and re-learning walks. Foragers and novices show differences in compass cues and behaviors, but remain magnetosensitive in cue conflict situations under manipulated panorama conditions.

Summary: The study found that the Johnston's organ (JO) in the desert ant Cataglyphis workers has a similar anatomy and central projection pattern to bees and fruit flies, exhibiting a multisensory nature that likely serves synchronization and calibration of different sensory modalities during navigation ontogeny.

Summary: The study introduces a continuous attractor network model with memory-dependent asymmetric synaptic connectivity, which can generate dynamic memory retrieval. The results show that the dynamic component does not impair memory capacity and can even enhance it in certain regimes.

Summary: The study developed requirements for optimal local path planning of autonomous ships by considering various scenarios and navigation practices, as well as the rules in COLREGs part B. These requirements can be used to improve existing path-planning algorithms and develop superior algorithms in the future.

Summary: We found that visually navigating ants display regular lateral oscillations coupled with variations of forward speed to optimize distance covered and scan left and right directions. This pattern of movement is produced endogenously and conserved across different ant species. The amplitude of the oscillations can be modulated by visual cues to adjust exploration/exploitation balance.

Summary: The study found that bumblebees are capable of using path integration and artificial celestial cues to accurately estimate vector distances and orient themselves within short distances. They also exhibit systematic search patterns when they fail to return accurately to their nests.

Summary: Ants establish foraging routes through learning views of the visual panorama. They rapidly learn and perceive aversive views, which trigger changes in behavior. A logarithmic relationship between captivity duration and hesitations suggests how aversive view learning could be executed within the mushroom bodies circuitry.

Summary: This study investigates how experience affects the behavior of ant workers towards pitfall traps. The study finds that ants improve their ability to detect and avoid traps after accumulating experience, and they can quickly adjust their behavior in response to changes in the environment.

Summary: This paper proposes a novel LiDAR-only ODOmetry and Mapping approach LiODOM for pose estimation and map-building by minimizing a loss function derived from a set of weighted point-to-line correspondences. It emphasizes on map representation and introduces a data structure combined with a hashing scheme for fast access to any section of the map.
