Extracting multiple observations in a C++ program

[SelinBayramoglu]

Hello all,

I am trying to use Ecole entirely within a C++ program. I am using the branching example in ecole/examples/libecole. The branching environment in the example extracts a single observation (NodeBipartite). I was wondering if you can share a method to extract two observation functions, for example NodeBipartite and Khalil2016. Many thanks in advance!
