Hello Shaon,<br>
<br>
SCIP does not have a dedicated function to query the total root node
time. You can query the time that was needed to solve the initial
root LP calling SCIPgetFirstLPTime(scip).<br>
<br>
If you want to know the total time that root node solving takes, set
a node limit of 1 to the solving process, such that it is
interrupted at the end of the root, and you can query the normal
solving time of SCIP using SCIPgetSolvingTime(scip).<br>
If presolving takes long, you may want to subtract
SCIPclockGetTime(scip->stat->presolvetime).<br>
<br>
After this, you disable the node limit and continue the solution
process as usual.<br>
<br>
Best,<br>

</div>
<div>In a branch-and-price method, I want to get the time for
solving the root node. </div>
<div><br>
</div>
<div>Is there any SCIP function for this value?</div>
<div><br>

<div>Thanks,</div>
