Struct YoshidaIntegrator 

pub struct YoshidaIntegrator { /* private fields */ }

Yoshida 4th order symplectic integrator.

Higher-order symplectic method with excellent energy conservation. Composed of three Verlet steps with specific coefficients.

Properties

• Order: 4
• Symplectic: Yes (preserves phase space volume)
• Time-reversible: Yes
• Energy drift: O(dt⁴) bounded oscillation
