This project is an educational and research-oriented implementation that benchmarks and compares different metaheuristic algorithms for solving VRPTW problems. The VRPTW is a classic NP-hard ...

A professional python hunter in Florida needed assistance from family members to uncoil a giant Burmese python from his body and to ultimately subdue the second-heaviest python ever caught in Florida.

Ants coordinate highly complex foraging and traffic systems without any leaders, relying entirely on local interactions and chemical cues. Pheromone trails encode information about distance, food ...

Scientists describe the behavior as "altruistic signalling," a form of social immunity in eusocial insects Getty A new research study finds infected ant pupae emit a chemical signal that prompts ...

Illness usually brings trouble in the animal world. A weak member may be pushed aside, attacked, or left behind. Many animals go to great lengths to hide sickness. But for creatures bound by family, ...

Ant pupae that are fatally sick don’t hide their condition; instead, they release a special scent that warns the rest of the colony. This signal prompts worker ants to open the pupae’s cocoons and ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Ants are some of nature’s most selfless animals. They practice ...

New research shows that terminally ill baby ants tell other ants to kill them, potentially protecting the rest of the colony from their infection. In a study published today in the journal Nature ...

For some would-be ant queens, the easiest way to take over a colony is to dupe its worker ants into committing regicide. The scientist E.O. Wilson once wrote that ants are the most warlike of all ...

The scientist E.O. Wilson once wrote that ants are the most warlike of all animals. He said clashes between ant colonies could make great military clashes seem almost small by comparison. Sometimes, ...
