<p>Hi,</p>
<p><br>
</p>
<p>A bit more info: I printed out the parents of that node and the node type of its parent is <span style="font-size: 12pt;">SCIP_NODETYPE_JUNCTION (</span><span style="font-size: 12pt;">fork without LP solution) :</span></p>
<p><span style="font-size: 12pt;"></span><span style="font-size: 12pt;">curr_node: 5085</span></p>
<p></p>
<div>parent1: 5082, type 6</div>
<div>parent2 5065, type 6</div>
<div>parent3 5061, type 8</div>
<div><br>
</div>
<div>The latest node that was entered before 5085 is 5065. For node 5065, I think scip already found an LP solution for it but somehow its type is still 6. And the branching tree jumped over 5082 to 5085 (both was not created by me). I would be grateful if
someone can explain to me the behavior. Thank you in advance.</div>

<p>Hi all,</p>
<p><br>
</p>
<p>During my branch and price implementation, I got a strange error: SCIP tried to enter a node that was not created before. I checked again all the time I used SCIPcreateChild and printed out the node number but that node was never created. Also, my program
is currently only at depth 4 but that node is at depth 9. Do you have any idea what might go wrong?</p>
