Is TimeLimit counting the cpu time or system time ?

Hello,

Gurobi can set the time limit by setting the parameter TimeLimit, but I am wondering is the Timelimit parameter set for total CPU time or system time (the time used to solving the model exclude the time formulating the problem)? 

Thanks.

  Hi Miranda,

  The TimeLimit parameter sets the maximum wall clock time (system time). The time used for model construction / reading of the model is excluded.

  Hi Jaromil,

  Is there a way to set a time limit by using CPU time?

  Thanks in advance,

  Hi Ozlem,

  There is currently no way to set the time limit via CPU time. You could check for the CPU time in one of the callbacks and terminate the optimization once a certain limit is reached. You would have to get the CPU time information from standard libraries.
