In the real world, ant colonies typically exploit one source then Two food sources are equidistant from the nest? When that happens Try different placements for the food sources. ![]() Take the ants to discover it? EXTENDING THE MODEL Long does it take the ants to create a path around it? If you makeĪ hole through the barrier (with REMOVE BARRIER), how long does it Try creating a barrier between a food source and the nest. See food3 which is on the upper left of the world. See food2 which is on the lower left of the world. You see food1 which is on the right side of the world. The consumption of the food source is shown in a plot. Sources require a larger “critical number” of ants to form a Once the colony finishes collecting the closest food, theĬhemical trail to that food naturally disappears, freeing up ants To form a stable trail to the more distant food, since theĬhemical trail has more time to evaporate and diffuse before being Starting with the food closest to the nest, and finishing with theįood most distant from the nest. The ant colony generally exploits the food source in order, Click or hold the mouseīutton to add food in particular places. Kind of food to be deposited (“cyan,” “sky,” or “blue”) isĭetermined by the FOOD-KIND chooser. The DEPOSIT FOOD button allows more food to be deposited. Hold the mouse button to draw or erase barriers. The REMOVEīARRIER allows some or all of the barriers to be erased. The ants and diffusion of the chemical and nest scent. The MAKE BARRIER button allows barriers to be drawn, which block The DISPLAY-FIELD chooser determines whether to display theĬhemical concentration or the nest-scent concentration. Turning off the plotting lets the model run faster. The DIFFUSION-RATE slider controls the diffusion rate of The EVAPORATION-RATE slider controls the evaporation rate of theĬhemical. The nest-scent in a red-to-white gradient. The chemical is shown in a green-to-white gradient, HOW TO USE ITĬlick the SETUP button to set up the ant nest (in violet, atĬenter) and three piles of food. As moreĪnts carry food to the nest, they reinforce the chemical trail. The chemical, they follow the chemical toward the food. The nest, dropping a chemical as it moves. ![]() When an ant finds a piece of food, it carries the food back to Each antįollows a set of simple rules, but the colony as a whole acts in a In this project, a colony of ants forages for food.
