A lot of time has passed by, more then a year, but I finally decided to put on-line something about the Red Queen Hypothesis research thesis ( life kept getting in the way).
of stigmergic systems, swarm intelligence and Embodied Embedded Cognition.
The project is developed with the aim of answering the increasing redevelopment request of abandoned post-WW2 buildings in northern Italy, proposing an alternative approach to requalification through processes of intrusion, adaptation and growth, focusing on the relationships between different systems (host/parasite) and innovative fabrication techniques.
Parasiting is a phenomenon where a system exploits resources from another system to thrive and replicate. The original system is not destroyed, however, it becomes an extension of the parasiting system. In order to revitalize an abandoned factory that has become an urban landmark for the community, a parasiting strategy has been implemented through agent based systems.
Agents’ cognitive capacities to perceive the environment, that is the driving factor for adaptation through indirect coordination, have been exploited to investigate emergent and adaptive morphological configuration of semi-rigid bodies, related to existing structures and systems.
Starting from the theoretical premises found in Jeff Jones' paper “Characteristics of Pattern Formation and Evolution in Approximations of Physarum Transport Networks”, the classical multi-agent system model has been extended with chemotaxic stigmergy (the capacity of perceiving and react to chemical gradients of concentration), which has been used as cognitive substrate for a continuous feedback loop with the environment (modeled as a discreet 3-dimensioal non-isotropic voxel field with tensor data in each voxel) and for indirect coordination between agents.
Space negotiation, emergent pattern formation and performative skills have been explored through simulations of multiple populations of agents, competing for resources.
Chemotaxic approach potential has been explored on a multiplicity of scales through a series of digital simulations ranging from volume morphogenesis to surface discretization.
stigmergic grammar from Paolo Alborghetti on Vimeo.
This simulation shows 2 populations of 2500 agents fighting for space negotiation in 2D environment, but “smelling” 3d pheromone field values. Each agent smells pheromone deposition from its population mates, but eat pheromone from the other one. Pheromone field act as communicative substrate for agents relationships ( no proximity calculations here).The bi-populate system grows on z axis, casting material and non-weaving trails networks during the movement.

This simulation shows further application of the stigmergic grammar applied to en existing abandoned building. Given some initial constraints ,a series of simulations have been performed ( isosurfacing the density field), producing a taxonomy of solutions , a catalogue of possible spatial configurations, between which choose the one that best fit space continuity and permeability criterias.
Softbody adaptation + EEC from Paolo Alborghetti on Vimeo.
At a larger scale Embodied Embedded Cognition (emergence of conscious and intelligent behaviour from the interaction of brain, body and world) has been experienced introducing topological shapes for the exploration of adaptive morphological capacities, through soft-body modules (via Verlet integration), instantiating agents over discrete spring-based mesh lattices. Soft-body morphologies are influenced (through gradients of spring stiffness modification) by continuous agent pheromone perception.
The final mesh configuration has been chosen after a long series of simulation on wide range of topologies with different genus. What 's been evident was that closed non-manifold meshes , was the best set up and led to more interesting spatial outcomes. Agents instanced on vertices are obliged to relate to agents / mesh vertices neighbour , avoiding mesh collapse ( often happening with open manifold meshes).
surface Growth from Paolo Alborghetti on Vimeo.
At a finer scale, thanks to the development of a custom strategy for mapping 2D simulation to 3d topological space through undistorted projections, surface's intricated tectonics are the result of multiple population of agents acting influenced by several parameters, including both performative and design-based ones.
Mesh vertices has been charged with different weight layers .Performative ones like radiation analysis (rgb values map ), FEA structural stress analys (rgb values map) . A third layer has been implemented to let the designer influence consciously the process of growth ( grey scale map, hand -painting weight mesh vertices). Proprieties and parameters of the agent cognitive system has been assigned to each weight layer (with the precise intent not to influence directly agents movements, but only their perception of the environment and their relationship with the data stored in the pheromone field).
Sensitive surface growth from Paolo Alborghetti on Vimeo.
Population of agents fight for space negotiation creating fiber-reinforced composites through two different methodologies: the first based on matter accumulation through additive deposition (compliant with contemporary additive manufacturing processes) and the second based on fibrous system through non-woven networks methodologies.
The purpose of the Red Queen Hypothesis is introduce in the computational design process increasing degrees of emergent behavior empowered by cognitive systems that are inevitably influenced by body consciousness (which is also a pivotal argument for AI cognitive protocols) and how this potential can be translated and exploited through contemporary fabrication methods (this last part is the object of future developments).
The work I just presented is just one of the multiple solutions, code logics, ideas, processes I developed and work on during the thesis period.(flickr gallery : https://www.flickr.com/photos/130523864@N03/).
Meanwhile because of the huge amount of time , and work, and life time I dedicated to this I decided to write a “Little list of receipes” for you guys , trying to highlight the mistakes I did, and the little tricks I learned from this experience.
So..here we go:
-always remember : not getting focus on one specific process/code/concept is always bad. Loose time on development of every single idea you come up with will probably take your thesis longer than expected . This is for sure the biggest mistake.
-Even if you are running totally speculative, keep in mind that you're not God or Tesla or what ever you want.
-don't stubborn on totally bottom-up ( I know that the Force is strong in you, but the dark side looks always even stronger) and too complex projects, mainly because of Control issues (which probably would deserve a whole post, given the importance of this topic). “messy computation “ (cit.), for example, could be a good alternative.
-share stuff as much as you can. Share images , videos, codes, processes.The more you give to the community, the more you get back.
-Don't kill your social life spending day and night on code.
-Try to live in a city / community/ collective of culturally active people ( architects, coders, artist, biologist, philosophers...).
-Keep on getting you work reviewed .I'm not talking about official reviews with your thesis advisor ( which by the way are always fundamental),but meet your code/arch /design friends in a pub, with your laptop on the table , sketching logics on pieces of paper.
-never give up.
