Parameters of ideal circadian cycle were compared with those of a circadian cycle composed of near-hour fluctuations. The integral cycle was optimized by the algorithm of matrix random search studying the approximation of its parameters to the ideal cycle after the phase shift of the latter. Computer calculations revealed a low efficiency of the search by fluctuation amplitude. The search by phase and frequency was effective in a narrow range of changes and needed time. The average level of fluctuations tuned up practically immediately: ideal and optimized curves coincided in all points. Examples of interactions between day, near-hour and shorter cycles are cited.
将理想昼夜节律周期的参数与由近似每小时波动组成的昼夜节律周期的参数进行了比较。通过矩阵随机搜索算法对积分周期进行优化，研究其参数在理想周期相移后与理想周期的近似程度。计算机计算表明，按波动幅度进行搜索效率较低。按相位和频率进行搜索在较窄的变化范围内有效且需要时间。波动的平均水平几乎立即得到调整：理想曲线和优化曲线在所有点上都重合。文中列举了日周期、近似每小时周期和更短周期之间相互作用的实例。
