Enables API call recording. When enabled, Gurobi will write one or
more files (named
gurobi000.grbr or similar) that capture the
sequence of Gurobi commands that your program issued. This file can
subsequently be replayed using the
Gurobi command-line tool. Replaying
the file will repeat the exact same sequence of commands, and when
completed will show the time spent in Gurobi API routines, the time
spent in Gurobi algorithms, and will indicate whether any Gurobi
environments or models were leaked by your program. Replay files are
particularly useful in tech support situations. They provide an easy
way to relay to Gurobi tech support the exact sequence of Gurobi
commands that led to a question or issue.
This parameter must be set as soon as you create your Gurobi
environment (or in a
gurobi.env file). All Gurobi commands
will be recorded until the environment is freed or the program ends.
Changing the parameter value back to 0 has no effect.
