    Hi Florian,

    I don't think so as the decision to branch and move to another node is made after cuts are added.  Perhaps as a workaround (depending on what you want to do) you could set the NodeLimit to 0, then the optimization will cease, then you do something with the last fractional solution recorded (by you), then change the NodeLimit value to something else, then call optimize() again to resume.
