It's still semi-documented in the last release: 
https://www.boost.org/doc/libs/1_76_0/libs/math/doc/html/math_toolkit/internals/minimax.html

This code is/was an internal detail that I used to generate the rational 
minimax approximations used in the library, the code should still be 
working so far as I know.

What did you want to know?
