Would the proofs just carry over?(Õâ¾ä»°Ã»¿´¶®Òâ˼£¿) - Also in the introduction, I would find it useful to first describe the simple mean-field rate equation solutions (in the absence of Brownian noise). These could then compared in Sec.5 with the numerical simulations. It seems that the population densities shown in Figs. 1-3 fluctuate about their mean given by basically the rate equation solutions. Are the associated variances given just be the noise correlator strengths? (simple mean-field rate equation solutions (in the absence of Brownian noise)Õâ¸öÀíÂÛ²»ÊìϤ£¬Çë¸ßÈËÖ¸µã£¡) - Are the plots obtained with just a single noise history realization each? Shouldn't there be averages over a sufficiently large number of noise histories? Are there periodicities in the data, which could be uncovered by temporal Fourier transforms? Are the predators in Fig. 3 truly becoming extinct? The data shown is not clear - there could be a population recovery as in earlier times. ¹Ø¼üËûµÄһЩÎÊÌâÎÒû¿´¶®£¬Çë´ó¼Ò°ïæ·ÖÎö£¬Ð»Ð»£¡ |
