“…The first concerns measurements. In game experiments, by considering the time reversal symmetry in high stochastic trajectories of social state motions, the observations of deterministic motions (e.g., cycle frequency [33,34,32], cyclic Payoff Matrix Replicator Projection Dynamics Dynamics motion vector field [35,36,37], and cycle counting index [17]) have been quantified, which led us to explore new measurements of dynamic patterns. The second development is in the domain of experimental technology, which has enabled the realization of continuous time experiments from which sufficiently long trajectories can be harvested [38,17].…”
