RESEARCH & LEARNING VAULT // Craig Reynolds Boids Swarm Intelligence & Topological Ecology

Autonomous steering behaviors, topological starling murmurations, 3-species predator-prey dynamics, and atmospheric updrafts.

ACADEMIC & ALGORITHMIC REFERENCE
// HISTORICAL ORIGINS

Introduced by computer graphics pioneer Craig Reynolds at ACM SIGGRAPH 1987 in 'Flocks, Herds, and Schools: A Distributed Behavioral Model'. Later refined by Andrea Cavagna's STARFLAG project (PNAS 2010), proving that starlings interact topographically with their 7 nearest neighbors rather than within a metric radius.

// GOVERNING EQUATIONS
F⃗net=wsF⃗sep+waF⃗ali+wcF⃗coh+wwF⃗wind+F⃗target\vec{F}_{net} = w_s \vec{F}_{sep} + w_a \vec{F}_{ali} + w_c \vec{F}_{coh} + w_w \vec{F}_{wind} + \vec{F}_{target}
// BROWSER IMPLEMENTATION

Each autonomous boid computes separation (repulsion from close neighbors), alignment (steer towards average heading), and cohesion (steer towards center of mass). Accelerated by a spatial hash grid with support for 5 exotic ecological and aerodynamic regimes.

// GUIDED EXPERIMENTS TO TRY IN THIS SANDBOXNORMAL
1Predator Hawk Panic Scattering

🎯 Action:Set Cursor Mode to '🦅 PREDATOR HAWK' and move mouse into the center of the dense flock.

✨ Observe:Observe the flock fracture into panicked micro-clusters performing rapid evasive flash expansion to escape the predator's kill radius.

2Murmuration Schooling Ribbon

🎯 Action:Select '🕊 MURMURATION' preset and observe autonomous ribbon turns.

✨ Observe:Boids form a synchronized fluid ribbon resembling a school of fish or starling cloud with high spatial coherence.

UNDISCOVERED

🎯 Action:Interact further.
