But that would make the functions non-inline, which seems to be what the OP
wants to avoid (inline for performance reasons I guess). However, if the
functions are complex enough that exposing them exposes the implementation
details of your algorithms, then I guess they're probably non-trivial
functions and should not be inline anyway. Therefore I like this
suggestion, though it does not have to be an abstract base class with pure
virtual functions, but rather any class with non-inline functions.

Also, off topic but worth mentioning: if the algorithms are that complex,
then consider getting patents on them.
