Abstract Interface

Those are the abstract classes you can inherit from to implement your own driver

AbstractDriver	Abstract base class for NetKet variational drivers.
AbstractOptimizationDriver	Base class for variational optimization drivers (VMC, SR, Infidelity, …).
AbstractDynamicsDriver	Abstract base class for time-evolution (dynamics) drivers.

For backward compatibility, AbstractVariationalDriver remains an alias of AbstractOptimizationDriver, but new code should use the canonical class names above.

Concrete drivers

Those are the optimization drivers already implemented in Netket. Regarding VMC (ground-state optimization), we reccomend to use VMC_SR instead of the normal VMC in most cases.

VMC	Energy minimization using Variational Monte Carlo (VMC).
VMC_SR	Energy minimization using Variational Monte Carlo (VMC) and Stochastic Reconfiguration/Natural Gradient Descent.
SteadyState	Steady-state driver minimizing L^†L.

State fitting

Infidelity_SR

Infidelity minimization with respect to a target state \(|\Phi\rangle\) (with possibly an operator \(U\) such that \(|\Phi\rangle \equiv U|\Phi\rangle\)) using Variational Monte Carlo (VMC) and Stochastic Reconfiguration/Natural Gradient Descent.
