| 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. |
