Abstract

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.

[生理节律和昼夜节律的相互作用。一个控制论模型]。
将理想昼夜周期参数与由近小时波动组成的昼夜周期参数进行了比较。采用矩阵随机搜索算法对积分循环进行优化,研究其参数在理想循环相移后逼近理想循环。计算机计算表明,通过波动幅度搜索的效率较低。基于相位和频率的搜索在较窄的变化范围内是有效的,并且需要一定的时间。波动的平均水平几乎立即调整:理想曲线和优化曲线在所有点上重合。列举了日周期、近小时周期和更短周期之间相互作用的例子。
