    Dear William,<br>
    <br>
    did you check <a class="moz-txt-link-freetext" href="http://scip.zib.de/doc-5.0.0/html/REOPT.php">http://scip.zib.de/doc-5.0.0/html/REOPT.php</a> ?<br>
    <br>
    Concerning SCIPchgVarObj and SCIPchgReoptObjective, the latter is
    particularly for the use during reoptimization applications. The
    former is for model creation or used during presolving, but cannot
    be called anymore after solving unless you free the complete
    transformed problem, which you do not want to do during
    reoptimization.<br>
    <br>
    Best,<br>
    Gerald<br>

                    I need to use the reoptimization feature of the
                    scip, but I hard to get the idea when I study the
                    api of reoptimization.<br>
                    <br>
                  </div>
                  So, would you please give me a whole view of
                  reoptimization api designing, and help me to use the
                  reoptimization feature.<br>
                  <br>
                </div>
                Thank you!<br>
