<p class="MsoNormal">I am using SCIP to solve a formulation via branch and price in which there are integer variables other than the ones that are priced out. For example, suppose there are integer variables X, which are enumerated and not priced out. Suppose
there are also binary variables Y, which are generated dynamically via pricing. <o:p>
</o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have implemented a branching rule that is like Ryan & Foster for when one of the Y variables are fractional. I’ve implemented this by modifying the Bin packing example code.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In the case where all the fractional variables at a node are the X variables (meaning not the ones that need to be priced out), I’d like my branching rule to basically defer to normal SCIP branching. How do I do that?<o:p></o:p></p>
