Self-organization - Wikiparency

# Self-organization Self-organization is the spontaneous emergence of global order from local interactions in an initially disordered system, driven by fluctuations, [[Positive_feedback|positive feedback]], and energy throughput without external blueprint. Dissipative structures, swarming, crystallization, morphogenesis, and market patterns exemplify the process across scales.  ## Microsims (promoted from legacy — three.js first) ### MicroSim spec - **Recommended sim type:** [[Agent-based_model|agent-based model]] - **Microsimmability score:** 84/100 - **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below. ### Parameters (tunable controls) - `Number of agents` - `Local rule strength` - `Noise` ### What animates Disordered agents following local rules spontaneously assemble into ordered global patterns. ### Learning objective Show how global order can emerge from local interactions without central control. ### MicroSim spec - **Recommended sim type:** self-organization - **Microsimmability score:** 87/100 - **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below. ### Parameters (tunable controls) - `Number of units` - `Coupling strength` - `Noise` ### What animates Disordered units lock into a coherent pattern as [[Coupling|coupling]] overtakes noise. ### Learning objective Show how order arises locally without a central controller.   ## Microsims — three.js ### Self-organization (three.js) <div class="microsim-player"> <iframe src="https://wikitube-3d-microsims.netlify.app/Self-organization.html" width="100%" height="620" frameborder="0" loading="lazy" sandbox="allow-scripts allow-same-origin" title="Self-organization — three.js microsim"></iframe> </div> **Open it full-screen:** [Self-organization.html](https://wikitube-3d-microsims.netlify.app/Self-organization.html) · library `threejs` · route `microsim/threejs/` ### Related microsims Live sims on neighbouring articles — 6 of them inside this article's own Wikipedia link tree: - [[Agent-based_model]] *(in tree)* - [[Complex_system]] *(in tree)* - [[Emergence]] *(in tree)* - [[Feedback]] *(in tree)* - [[Network_theory]] *(in tree)* - [[Phase_space]] *(in tree)* *Sim hosted off-article; the article owns the reference, not the runtime (WIKI_RULES §10.4).

In the language of the [[Dynamical_system|dynamical system]], order is an attractor of a [[Nonlinear_system|nonlinear]] flow; in the [[Complex_system|complex system]] it is the twin of [[Emergence|emergence]] at the edge of [[Chaos_theory|chaos]]. The pattern repeats wherever parts organize themselves: an [[Ecosystem|ecosystem]] assembling through [[Population_dynamics|population dynamics]], swarm computation in the [[Agent-based_model|agent-based model]] and [[Cellular_automaton|cellular automaton]], learning in the [[Neural_network_(machine_learning)|neural network]] and the [[Genetic_algorithm|genetic algorithm]], structure formation on the [[Network_theory|network]], and market order studied by [[Economics|economics]] and [[Systems_science|systems science]]. ## Wikipedia : Wikitube **Strict pair:** [Wikipedia](https://en.wikipedia.org/wiki/Self-organization) : [Wikitube](https://en.wikitube.io/wiki/Self-organization) ## Previous hub tags Hubs: `Systems`.
