PRM format
A Gurobi parameter (PRM) file is used to specify parameter settings. Reading a parameter file (using GRBread, for example) causes the parameters specified in the file to take the specified values.
The file consists of parameter-value pairs, each on its own line. Any line that begins with the hash sign (#) is a comment line and is ignored. The following is a simple example:
# Parameter settings Cuts 2 Heuristics 0.5
If an unknown parameter name is listed in the file, a warning is printed and the associated line is ignored.
Note that when you write a Gurobi parameter file (using GRBwrite in C, Model.write in Python, or in any of the other APIs), both integer or double parameters not at their default value will be saved, but no string parameter will be saved into the file.
