Nature-inspired heuristics are problem-solving methods modeled after natural processes. Like how birds flock or bees forage, these algorithms mimic nature to tackle complex problems. They use strategies like evolution, ant colony behavior, or bird flocking to find good solutions, blending randomness with specific rules from nature. These methods are useful for tough problems where traditional approaches might fail, creatively applying nature's wisdom to areas like computer science, engineering, and logistics to find efficient, often surprising, solutions.
