## TL;DR
Swarm and evolutionary intelligence describes optimization methods inspired by social behavior and evolution. Strong claims should identify the algorithm family instead of treating all bio-inspired search as one technique.

## Core Explanation
Particle swarms, ant-colony methods, and genetic algorithms all search over candidate solutions, but they differ in representation, update rules, and how they use population-level information.

## Detailed Analysis
The repaired article uses classic PSO, ant-colony, and genetic-algorithm sources and avoids broad claims that these methods are always superior to conventional optimization.
