Mutation rate

A population of candidate solutions is scored by fitness (bright = high). The fittest are selected, crossed over, and mutated each generation. Watch the swarm climb toward the global peak while dodging local optima.

Governing equation

P_{i} = \frac{f _{i}}{\sum _{j} f _{j}}, μ = 0.08, f_{m a x} = 0.000

Reading this result: Balanced mutation (0.08) with population 80: enough diversity to escape local optima while still converging — the classic explore-vs-exploit sweet spot.
