Eberhart & Kennedy 1995 PSO with the standard inertia-weight update:
v[i,t+1] = w·v[i,t] + c1·r1·(pbest[i] - x[i,t]) + c2·r2·(gbest - x[i,t])
x[i,t+1] = clamp(x[i,t] + v[i,t+1], bounds)
Single-objective only, `Vec<f64>` decisions only (PSO's velocity vector
needs a Euclidean structure that doesn't generalize cleanly to bool/perm).
Velocities are clamped to ±(hi - lo) per dim to keep particles from
exploding off into space.
Config exposes the four standard knobs — swarm size, generations,
inertia w, cognitive c1, social c2 — plus a seed. Tests cover
convergence on Sphere1D, deterministic reruns, and panic on
multi-objective.
