Pseudocode No The paper describes mathematical equations and derivations for the learning dynamics (e.g., Eqs. (1) and (2)) but does not present them in a structured pseudocode or algorithm block format.
Open Source Code Yes Code https://github.com/Cyber Agent AILab/ periodic games synchronization
Open Datasets No The paper uses simulated game environments such as 'periodic matching pennies' and various 'matrix games' (2x2, 3x3, 6x6) for its experiments. It does not refer to or provide access information for any external, pre-existing public datasets.
Dataset Splits No The paper simulates learning dynamics in defined game environments rather than using pre-existing datasets with explicit training/test/validation splits.
Hardware Specification No The paper describes the numerical method used for simulation (Runge-Kutta fourth-order method) but does not provide any specific details about the hardware (e.g., GPU models, CPU types, memory) on which these simulations were executed.
Software Dependencies No The paper mentions using the 'Runge-Kutta fourth-order method' for simulations, which is a mathematical algorithm. However, it does not specify any particular software libraries, programming languages, or other dependencies with version numbers used for its implementation.
Experiment Setup Yes To simulate the learning dynamics, we use the Runge-Kutta fourth-order method with a step size of 1/40. The initial strategies are set to the Nash equilibrium of the time-average game. The numerical method is the same as Fig. 1 but the step size is 1/(4 103).
