Ant colony optimization (ACO) is a relatively new random heuristic algorithm inspired by the behavior of real ant colony. It has been applied in many combinatorial optimization problems and the ...

Recent studies have examined the role of personality (consistent inter-individual variation in behavioral traits) during ant foraging. Since colonies differ from each other in the distribution of ...

No other needle ant colonies have been confirmed in Ohio since 2017 in Cincinnati. "We still do not know if the Asian needle ant colony was a 'one-off' occurrence with a single population now ascended ...

Fire ants are a common nuisance in Tennessee lawns, infesting residential neighborhoods, schools, playgrounds, golf courses, parks and more.

Asian needle ants, an invasive species making news around the country, were found in Providence in 2015, but there's no sign they ever spread.

While the ants are mainly stretching from Arkansas to New England, outliers have also been discovered in Washington state. Asian needle ants are small, measuring about 0.2 inches in length ...

USDA researchers submitted a manuscript to bioRxiv about the high U.S. colony losses in the United States in 2025 caused by the parasitic varroa mites, calling for new control strategies for the ...

This paper presents an improved adaptive ant colony algorithm in response to the drawbacks of the basic ant colony algorithm for robot path planning within grid environments, including low search ...
