Inter-bit sampling interval dependency. (a) Four kinds of reward probability arrangements in the four-armed bandit problem. (b) Effects of the temporal structure inherent in laser chaos on the decision-making performance, which can be negative or positive depending on the given problem. (c) Evaluation of a moderate inter-bit sampling interval choice based on the coefficient of variation (CV) of (a). Δ_L = 30 ps or 100 ps yields a lower CV for the Chaos 3 case. Meanwhile, the unstructured time-domain properties of pseudorandom numbers are clearly shown by the flat dependency on Δ_L in the RAND case.
