Digital Ant Colony System

30.09.2002


Whoever thinks that ants are only erratic little beings, whose incessant wanderings are pointless or obey no kind of universal order, is very much mistaken. Their society is so organized and complex that it is already being used as a model for the creation of algorithms, adaptable to a variety of scientific areas.

Inspired by the work of Chialvo and Millonas – the creators of the first numeric simulation according to which the formation of collective cognitive maps of social insects can be explained -, Vitorino Castelo Ramos, a young Portuguese researcher in the area of Artificial Research and Image Analysis, has developed a computational model that has a direct application to habitats of digital images.

More than simply reacting to the environment presented to them (any image digitally inserted as substratum), the digital ants of these colonies develop the capacities of sensing objects and outlines just like real ants do, adapting themselves to any digital environment.



After publishing the scientific work about the application of the "Ant colonies Systems" for the classification of databases and document clustering in February 2002, Vitorino Ramos has continued to dedicate himself to the development of algorithms that allow the practical application of this model.

An example of this are the algorithms that imitate the Stigmergy phenomenon – or rather, a certain environmental synergy that translates into the organization of ant colonies in different spatial groups – like the behaviour of real ants, with Data Mining applications.

Apart from serving as a base for the notion of the first operators of completely distributed, adaptable and self-organized Mathematical Morphology, the "Ant colony System" has many other possible applications, such as on an architectural and urban planning level or also for painting done by robots.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
