While no details have been officially published it was said that this is "a Romberg method" with a modified way of sampling the function values.

In the front of the Advantage ROM manual (p. 2), it states:

Quote:The root-finding and numerical-integration routines in this pac were
adapted from those in the HP-15C by Firmware Specialists, Inc., 605 NW
5th Street #2A, Corvallis, Oregon 97330.

Probably as close to official as these things get.
