Binary vs Integer Variables

[stumarcus314]

If the variables in my optimization problem are all binary, is there any difference internally to NOMAD between specifying them as binary by setting BB_INPUT_TYPE to (B B B) versus specifying them as integers by setting BB_INPUT_TYPE to (I I I) with lower bounds 0 and upper bounds 1? For example, does specifying them explicitly as binary using the first approach realize computational and/or memory efficiencies for NOMAD?

With the default mesh and direction type used by Nomad, binary variables are converted into integer variables (granularity 1) with 0 and 1 bounds.
Other direction types maybe developed in the future that handle binary differently.
