I want to analyze the daylighting in DesignBuilder but I have some problems with the basics. Are there any sources that can help me find the answers to following questions? 
 
     
  1. What is ray tracing method? 
    2.  
  2. What is Monte Carlo method used for in Radiance Daylighting? 
    3.  
  3. and I also want to know the detailed definition of ambient parameters (ambient bounces, ambient accuracy, ambient divisions, ambient super samples). I read DesignBuilder documentation but I didn't really get what they mean. 
    4.  
 
Thank you for any help that you can give.

The most comprehensive resource to understand Radiance is still "Rendering with Radiance," which is available as a $7 US PDF download or in soft cover from: https://www.radiance-online.org/learn...
 
You can also access the first chapter, which is a decent introduction, directly from the website.  For the details, you will need the later chapters that discuss the methods and parameters, although I can recommend one of John Mardaljevic's presentations to get you started, such as: https://www.radiance-online.org/commu...
 
I also like Raphael Compagnon's daylighting tutorial from way back in 1997:  https://floyd.lbl.gov/radiance/refer/...
 
Best,
