  We develop a generalized hyperdynamics method, which is able to simulate slow
dynamics in atomistic general (both energy and entropy-dominated) systems. We
show that a few functionals of the pair correlation function, involving
two-body entropy, form a low-dimensional collective space, which is a good
approximation that is able to distinguish stable and transitional
conformations. A bias potential, which raises the energy in stable regions, is
constructed on the fly. We examine the slowly nucleation processes of a
Lennard-Jones gas and show that our new method can generate correct long time
dynamics without a prior knowledge.
