<div class="moz-cite-prefix">Dear Xiangyong Li,<br>
<br>
if you know that every feasible solution will have an integer
objective value and therefore want to stop the solving process
when the dualbound is larger than primalbound - 1, you can just
inform SCIP that this is the case by calling SCIPsetObjIntegral().<br>
<br>
Otherwise, you can call SCIPinterruptSolve() to stop the solving
process, but SCIP will then print that it was interrupted, not
that it was solved to optimality.<br>

<div><br>
</div>
<div>I am using SCIP to implement my branch and price algorithm.</div>
<div><span style="font-size: 12pt; line-height: 1.5;
background-color: window;">Now I want to terminate the SCIP
earlier since I can judge the problem has been optimally
solved when some condition is satisfied. </span></div>
<div>Suppose UB and LB be the objective value of best incumbent
and the best remaining node in the branch and bound tree.</div>
<div>For my instances considered, SCIP has optimally solved one
instance if UB-LB < 1.</div>
<div><br>
</div>
<div>Can you tell me how to set the earlier termination condition
in SCIP?</div>
<div><br>
</div>
<div>Thanks,</div>
