Modulation of trail laying in the ant Lasius niger (Hymenoptera: Formicidae) and its role in the collective selection of a food source
TLDR
Simulations of this model showed that the observed modulation of trail laying with respect to food source quality is sufficient in itself to account for the systematic selection of the richer source seen in the experiments.Abstract:
Foragers of the ant Lasius nigerexploiting a 1 Msugar source were found to lay 43 %more trail marks than those exploiting a 0.05 or a 0.1 Msource. The trail laying per forager decreased during the course of individual recruitment episodes, and the mean lifetime of the trail pheromone was estimated to be 47 min. A mathematical function describing the probability that a forager chooses one of two paths in relation to the amount of trail pheromone on them closely fitted experimental data. These results were incorporated into a model describing the recruitment dynamics of L. niger.Simulations of this model showed that the observed modulation of trail laying with respect to food source quality is sufficient in itself to account for the systematic selection of the richer source seen in the experiments.read more

Coupling Ant Colony System with Local Search
TL;DR: The Ant Colony System (ACS) is presented which has been inspired by the observation of real ant colonies and some modifications of the original ACS algorithm are introduced to speed up the method and to make it more competitive in case of large problem instances.
Floral visitors and ant scent marks: noticed but not used?
TL;DR: It is demonstrated that, while naive bumblebees in laboratory trials are not inherently repelled by ant scent marks, they can learn to use them as informative signals while foraging on artificial flowers.

The Initial Behavioral Sequences and Strategies of Various Ant Species During Individual Interactions with Solenopsis invicta
Asha Rao,S. Bradleigh Vinson +1 more
TL;DR: The behavior of individual ants during one-on-one interactions is studied to gain insight into how resident ant species behave when they encounter incipient red imported fire ant, Solenopsis invicta Buren colonies.

Ant Colony Optimization in Stationary and Dynamic Environments
TL;DR: This thesis proposes a novel approach, called direct communication (DC) scheme, that helps ACO algorithms to escape from a local optimum if they get trapped, and shows that each proposed algorithm performs better in different dynamic cases, and that they have better performance than other peer ACOgorithms in general.
Variation and organization in social behavior : infectious disease and human intergroup conflict and warfare; and the organization of foraging behavior in harvester ants
TL;DR: An effort to explain geographic variation in the frequency and intensity of human civil conflict; and an effort to describe and model the foraging behavior of colonies of harvester ants of the genus Pogonomyrmex are presented.

The self-organizing exploratory pattern of the argentine ant
TL;DR: A minimal model shows how the exploratory pattern may be generated by the individual workers' simple trail-laying and -following behavior, illustrating how complex collective structures in insect colonies may be based on self-organization.

Collective decision-making in honey bees: how colonies choose among nectar sources
TL;DR: It is suggested that honey bee colonies possess decentralized decision-making because it combines effectiveness with simplicity of communication and computation within a colony.

Trails and U-turns in the Selection of a Path by the Ant Lasius niger
TL;DR: The selection of the path is shown to be a collective process whereby trail laying and following amplifies small initial differences in the traffic on each path caused by these three mechanisms, and the foragers show no significant tendency to follow the path they used previously.

Collective decision making through food recruitment
TL;DR: A series of experiments shows how the andLasius niger uses its trail recruitment system to select between two food sources, simultaneously presented with to 1M sucrose solution and when offered a 1M solution together with a 0.1M solution.

TL;DR: In this article, the authors present a model that describes the honey bee colony's decision-making process, which consists of a system of non-linear differential equations describing the activity of the foraging bees.
