It can be applied to any other animal that exhibits swarm behavior. Swarm intelligence is the collective behavior of decentralized, self-organized systems, natural or artificial. The basic idea of swarm intelligence is a “popula- tion” of local interactions to the environment in a greater amount that creates a global system. At 1989, the swarm intelligence expression was first introduced at robotic sys- tems, which describe the emergent collective behavior. Nowadays this new ap- proach of collective behavior has diversely implemented in many perspective from biology, social structure, engineering, artificial, visualization and architec- ture. What’s more, a collection of people can also exhibit swarm behavior, such as pedestrians. From the book, “Emergence”, by Steven Johnson, he also wrote about creating a “form” of living on having emergence logic from the smallest scale as ants into a larger scale as cities. He tries to define how the swarm logic of ants’ behavior could give example of the way of living for human level. For architects, swarm intelligence examines the role of agency within gener- ative design processes. Digital parametric programs like processing are used to make high populations of self-organized elements into an emergent intelli- gence. The gold is to explore the dissolution of modernist tectonic hierarchies. The research about application of swarm principles at architecture ranges from visualization, self-organization of multi-agent system, architecture form de- sign, urbanism, etc. Based on the boids system at the digital animation tool, we can simulate the swarm activity, translate the animal particle system with architecture tecton- ic system and research about architecture form, structure and space. Swarm could be generated into an architecture design method. 2 1.2 Swarm Behavior (http://en.wikipedia.org/wiki/Swarm_behaviour) As a term, swarming is applied particularly to insects, but can also be applied to any other animal that exhibits swarm behaviour. The term flocking is usually used to refer specifically to swarm behaviour in birds, herding to refer to swarm behaviour in quadrupeds, shoaling or schooling to refer to swarm behaviour in fish.

Prodöhl1 Received: 20 April 2017 / Accepted: 26 September 2018 / Published online: 10 October 2018 © The Author(s) 2018 Abstract Given their cryptic behaviour, it is often difficult to establish kinship within microchiropteran maternity colonies. This limits understanding of group formation within this highly social group. Following a concerted effort to comprehensively sample a Natterer’s bat (Myotis nattereri) maternity colony over two consecutive summers, we employed microsatellite DNA profiling to examine genetic relatedness among individuals. Resulting data were used to ascertain female kinship, parentage, mating strategies, and philopatry. Overall, despite evidence of female philopatry, relatedness was low both for adult females and juveniles of both sexes. The majority of individuals within the colony were found to be unrelated or distantly related. How- ever, parentage analysis indicates the existence of a number of maternal lineages (e.g., grandmother, mother, or daughter). There was no evidence suggesting that males born within the colony are mating with females of the same colony. Thus, in this species, males appear to be the dispersive sex. In the Natterer’s bat, colony formation is likely to be based on the benefits of group living, rather than kin selection.

  • Dispersal, Philopatry, and the Role of Fissionfusion Dynamics In
    MARINE MAMMAL SCIENCE, **(*): ***–*** (*** 2012) C 2012 by the Society for Marine Mammalogy DOI: 10.1111/j.1748-7692.2011.00559.x Dispersal, philopatry, and the role of fission-fusion dynamics in bottlenose dolphins YI-JIUN JEAN TSAI and JANET MANN,1 Reiss Science Building, Rm 406, Department of Biology, Georgetown University, Washington, DC 20057, U.S.A. ABSTRACT In this quantitative study of locational and social dispersal at the individual level, we show that bottlenose dolphins (Tursiops sp.) continued to use their na- tal home ranges well into adulthood. Despite substantial home range overlap, mother–offspring associations decreased after weaning, particularly for sons. These data provide strong evidence for bisexual locational philopatry and mother–son avoidance in bottlenose dolphins. While bisexual locational philopatry offers the benefits of familiar social networks and foraging habitats, the costs of philopatry may be mitigated by reduced mother–offspring association, in which the risk of mother–daughter resource competition and mother–son mating is reduced. Our study highlights the advantages of high fission–fusion dynamics and longitudinal studies, and emphasizes the need for clarity when describing dispersal in this and other species. Key words: bottlenose dolphin, Tursiops sp., association, juvenile, philopatry, locational dispersal, mother-offspring, ranging, site fidelity, social dispersal.

  • Swarming (Bulletin #404) (PDF)
    Swarming Apiculture Bulletin #404 Updated: 10/15 Swarming is a natural method of honeybee colonies to reproduce, resulting in the creation of a new honeybee colony in addition to the established colony. Contributing factors to swarming • Crowding - too many bees, food stores and no cell space for the queen to lay eggs in. • Poor air circulation • April-May is swarming season and healthy colonies develop strong swarm impulse. • Inclement weather - crowded bees confined by cold, wet weather will build queen cells and swarm out on the first sunny, warm day. All colonies in similar condition will swarm as soon as weather becomes favorable. • Large amount of drone brood in early spring is a precursor to strong swarm impulse. Catching the swarm A swarm generally emerges from the hive between 11:00AM and 1:00PM and settles close to the apiary for several hours. Allow the swarm to cluster for at least 30 minutes before placing the swarm in a single super with frames, bottom board and hive cover. Leave the hive for the remainder of the day to allow all the bees to enter, before moving to a permanent location. Examine the new colony after a week and then every two weeks from mid May to late June. Look for disease, brood abundance, brood pattern and overall condition of the colony. Add room where necessary, cut queen cells, or divide, to prevent other swarms to develop. Hived swarms have no stored food reserves and may go hungry when there is little forage. When feeding sugar syrup, add antibiotics as a precautionary measure.

  • Evolving Behaviour Trees for Supervisory Control of Robot Swarms
    Evolving Behaviour Trees for Supervisory Control of Robot Swarms Elliott Hogg1y, Sabine Hauert1, David Harvey, Arthur Richards1 1Bristol Robotics Laboratory, University of Bristol, UK. E-mail: [email protected], [email protected] Abstract: Supervisory control of swarms is essential to their deployment in real world scenarios to both monitor their operation and provide guidance. We explore mechanisms by which humans might provide supervisory control to swarms and improve their performance. Rather than have humans guess the correct form of supervisory control, we use artificial evolution to learn effective human-readable strategies to help human operators understanding and performance when con- trolling swarms. These strategies can be thoroughly tested and can provide knowledge to be used in the future in a variety of scenarios. Behaviour trees are applied to represent human readable decision strategies which are produced through evolution. We investigate a simulated set of scenarios where a swarm of robots have to explore varying environments and reach sets of objectives. Effective supervisory control strategies are evolved to explore each environment using different local swarm behaviours. The evolved behaviour trees are animated alongside swarm simulations to enable clear under- standing of the supervisory strategies. We conclude by identifying the strengths in accelerated testing and the benefits of this approach for scenario exploration and training of human operators.

It is designed to be an easily viewed, intuitive, button-based way of entering observations while letting the computer take care of associating each entry with the necessary but intensive logistical data (time, gps coordinates, current conditions, observers on board, effort status, etc.). The forms are designed to be navigated by using the mouse, using the tab key, or using the touch screen. It is also designed to output these data in a single file that can serve as both a raw record of the day's work and a single source from which to draw certain types of data (e.g. locations of hydrophone recordings and the locations of sighted whales). These, at least, were my intentions. The program was written in Visual Basic 2010 Express and published as a stand-alone executable file (.exe) for Windows. The program outputs text files to a folder it creates on the C directory of your computer. In addition to making this program available to others, I have provided the project files for the program, as well as my R scripts for analyzing the output text files, on my website.

University of Pune August 2014 Committee Chair: Dr. Manish Kumar, Ph.D. Abstract Robot Swarm based on Ant Foraging Hypothesis with Adaptive Levy´ Flights by Aditya Milind Deshpande Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Master of Science Degree in Department of Mechanical and Materials Engineering University of Cincinnati June 2017 Design of robot swarms inspired by self-organization in social insect groups is currently an active research area with a diverse portfolio of potential applications. This thesis is focused on the development of control laws for swarm of robots inspired by ant foraging. Particularly, this work presents control laws for efficient area coverage by a robot swarm in a 2D spatial domain, inspired by the unique dynamical characteristics of ant foraging. The novel idea pursued in the effort is that dynamic, adaptive switching between Brownian motion and Levy´ flight in the stochastic component of the search increases the efficiency of the search and area coverage. The study is motivated by behaviors of certain biological studies who exhibit searching patterns modeled using Levy´ flight. Influence of different pheromone (the virtual chemotactic agent that drives the foraging) threshold values for switching between Levy´ flights and Brownian motion is studied using two performance metrics - area coverage and visit entropy.
