algorithmic modeling for Rhino

Question: why every time the simulation results is not the same?

Thanks for the amazing work of Mostapha. But I find a question. Every time i run the daylight simulation, the results are different. For example, in the attached file, the average DF is 3.18% , but the value may be 3.17% next time. The question troubles me. Do you seen the problem? And who can tell me the reason. Thanks.

Daylight simulation is stochastic. For every data point, Radiance throws out n rays in random directions, and running the same simulation multiple times means that different rays are fired. So a small deviation is normal.
