generation

This keyword sets the number of generations $N_{\mathrm{gen}}$ for the SNES algorithm [Schaul2011]. The syntax is:

generation <number_of_generatinons>

Here, <number_of_generations> sets $N_{\mathrm{gen}}$, which must satisfy $0\le N_{\mathrm{gen}}\le {10}^7$ and defaults to $N_{\mathrm{gen}}={10}^5$. For simple systems, $N_{\mathrm{gen}}={10}^4\sim {10}^5$ is enough. For more complicated systems, values in the range $N_{\mathrm{gen}}={10}^5\sim {10}^6$ can be required to obtain a well converged model.
