The self-replication of light-sensitive nanoparticle dimers has an optimal rate of replication under pulsed, noncontinuous energy inputs, as shown by B. A. Grzybowski, M. O. de la Cruz, et al. in their Communication on page 173 ff. The optimization of self-replication does not necessarily require constant energetic expenditure; instead what matters is the proper timing with which the energy is delivered to the system.
