<br>
branching is done as part of the enforcement of LP (or pseudo)
solutions. The enforcement callback of the integrality constraint
handler calls the branching rules by decreasing priority. But any
other constraint handler with active constraints can also do
branching.<br>
<br>
Thus, you can implement your own constraint handler which checks
whether you need to do branching in the CONSENFOLP callback. You
should add one constraint of this handler which stores the data
needed to check feasibility.<br>
<br>
Note that the enforcement callbacks of constraint handler are
called in decreasing priority until one did perform a branching.
So you could even mix branching on integer variables with other
branching by your own constraint handler. If your constraint
handler has a positive priority, it will always be called before
the integer variable branching, otherwise afterwards. In your
case, however, I would recommend to just define your variables as
continuous.<br>

<p>Hello list,</p>
<p>I have to develope a Ryan and Foster Branching similar to the
binpacking one. The difference is that when I finish my
branching I cannot assure integrality on the variables. But I
don't have to, since I'm able to build a solution for my problem
easily.</p>
<p>It is possible to force the problem to go to the branching when
I define my variables as continuous? If not, is there a way to
just use my branching and no the default branching?</p>
<p>Best.</p>
<p>Diego.</p>
