Why do ants release pheromones according to the length of the pathWhy is the longer the path, the lo

Ant colony algorithm. Ants find the shortest path thanks to pheromones.

and the environment, suppose there are two paths leading from the nest to food, and the number of ants on the two roads is about the same at the beginning: when the ants reach the end point, they will return immediately, and the ants on the short road will have a short round trip time, and the repetition frequency is fast, the number of ants traveling back and forth in a unit time is more, and the pheromones left are also more, which will attract more ants to come and leave more pheromones. The opposite is true for long distances, so more and more ants are congregating on the shortest paths.

Ants use the smell of secretions to communicate, because they usually live in a nest, so this way of communication is better developed than other hymenopteran insects, if an ant finds food, it will leave a smell on the way home, and other ants will follow this route to find food, and constantly strengthen the smell. If the food is collected and there are no ants coming back, the smell will gradually dissipate. If an ant is crushed, it will emit a strong smell that immediately alerts other ants and is all in a state of attack.

Some species of ants also emit a scent that confuses enemies. Ants, like other insects, rely on their antennae to distinguish smells, and the first segment of the antennae is swollen and knee-shaped, making them very flexible. Because the antennae are a pair, they can distinguish the intensity of the smell, but also the direction of the smell, and the adults exchange food with each other, and learn about each other's health and nutritional status through their smells, and the food found by each other.

At the same time, it can also distinguish the group that the other party belongs to that kind of task, such as digging holes and building nests, or collecting food. The queen also constantly secretes a scent, and once this smell stops, the worker ants breed a new queen.

I don't know if it helps you......

Because the information of different paths is different, the probability of transferring to each path is also different.

Eh: You have to go to the professional ** to find it.

Ants rely on their sense of smell to identify their routes, and sunlight to discern directions.

The antennae of an ant are more agile than a blind man's bamboo pole. Because this pair of antennae has two functions: one is the tactile effect, through the contact with the outside world, you can detect the contour, shape and hardness of the object in front, as well as the terrain undulation of the road ahead.

This effect is exactly the same as that of a blind man's bamboo pole. The other is olfaction, which is identified by smell. This is something that the blind man's bamboo pole does not have.

It turns out that while walking, ants continue to secrete a small amount of chemicals with a special smell from the glands at the end of their abdomen and legs, called marker substances, which are contaminated on the road and leave traces. Nest ants far away from the nest, when they return to the nest, they use their special nose - antennae to smell this smell sign, which is called "scent navigation".Use your fingers to rub the ant vigorously several times on its way home to destroy its original chemical odor signpost, or put a sanitary ball and let the scent of the sanitary ball cover the smell of the marker substance.

At this time, you will see many ants crawling to this place, and then immediately stop moving forward and make a mess on the spot. Because they can't smell the original smell for a while, they are temporarily lost. If you continue to observe, you will find that after a short time, they touch each other with their antennae, as if they are talking to each other

The road sign ahead has been destroyed, and we have to find a way to do it quickly".They stop and go, going around in circles. Eventually, they will try to bypass the odor line and re-establish a new route back to the nest.

How did the ants rebuild the new road signs? In general, another means of positioning is used. That is, relying on the position of the sun and using polarized light in the sky to navigate, also known as astronomical road signs.

This secret was discovered a long time ago by the French entomologist Fabre. The eyes of ants are natural polarized navigators. Foraging ants can accurately return home by recognizing the direction of the sun and counting steps.

The actions of the ants are always united, as if they all have taken action ** to keep in touch at all times, what magic weapon do they have? Ants do have their own way of contacting their companions. Although they scattered around foraging for food, if anyone found food, in addition to quickly carrying a small piece back to the nest, they would also remember to secrete aromatic signals along the way, and urgently notify their companions to come to help.

Ants that smell the scent nearby will sniff the aromatic route all the way to find food, and one by one they will work together to carry all the food back to the nest. The ants that move along the scent form a long line, moving forward in an orderly manner. This aromatic substance secreted by ants is called pheromones, and because of its high volatility, after a few minutes, the food is transported back to the nest, and the fragrance disappears, so that no more ants will come and the result will be empty.

Their pheromones are like the ** in our hands, and although they are not as good as our mobile phones, they also have a lot of features. If there is food in front of you, you will be notified that there is danger in front of you, etc. The same notification, but the types of pheromones are different.
