Dear Gurobi developers

I firstly would like to thank all the members who have been working hard to solve problems of GUROBI users. You all are really expertise in your domain and provide accurate solution to what is being asked as it happened many time in my case.

I am actually looking forward to understand the each nomenclature used in the GUROBI log file. For example Matrix range, Qmatrix range........presolved removed, presolved time.......root relaxtion, nodes, current node, objective bound etc. shown in the picture below:-

 

Also from the objective solution I would like to know more about Gomory:13 , cover:3 etc shown in the picture below:-

I don't need you to explain everything but Is there any article where I can read understand what these nomenclature exactly mean as described above?

Your feedback would be highly appreciated.
