Frequently Asked Questions

What is swarm intelligence?

The collective, decentralised behaviour of many simple agents, such as ants, bees, birds or robots, that produces intelligent group results without central control.

Which swarm algorithm should I use?

Particle swarm optimization is the usual start for continuous problems; ant colony optimization suits routing and combinatorial problems; try several through MEALPY, Nevergrad or NiaPy and compare on your own objective.

Which libraries are good for beginners?

PySwarms for PSO, scikit-opt for a compact set of algorithms, and DEAP or Nevergrad for broader evolutionary work.

How does this relate to AI agent swarms?

Swarm intelligence supplies the ideas of decentralised coordination; LLM agent swarm frameworks apply similar patterns to AI agents, covered on the AI Agent Swarm Frameworks page.
