Hi

I want to know if the ordered branching conditions for a search tree node ( in a MIP search tree)   are available via the Java APIs.

Thanks!

  if the root node branches on binary variable  x1 to create 2 child nodes C1 and C2

  then C1 branches on binary variable y1 to create leafs C3 and C4

  I want to find out, at node C4, that it was created using  the branching conditions  x1=0 and y1=1

  also, it would be great if I knew the order in which variables were branched in order to create a leaf node. In the above example, the order was x1=0 and then y1=1
