CP-SAT | OR-Tools: Get existing variable by name?

Is it possible to get an existing variable by its name? Something like:

model = CpModel()
model.new_bool_var("mySuperBoolVar")

# ...many lines later...

bv = model.get_bool_var_by_name("mySuperBoolVar")

Obviously, get_bool_var_by_name() doesn't exist. There's only model.get_bool_var_from_proto_index(), but I have no idea what does it do...

Solution

  • No, you will need to do the bookkeeping yourself.

    Each variable has an index. Look at the clone model sample where it is used.
