Craig Interpolation API

Question

There are versions of the Z3 SMT solver that support Craig interpolation. Methods of the API where, for example, Z3_interpolate, Z3_write_interpolation_problem, or Z3_mk_interpolation_context.

Microsoft Research provides a website with the description of the Z3 C API! The methods that are listed above cannot be found in this documentation. Have this methods been removed? Can they be found in a specific branch of Z3?

The code can be found (as of today; the code changes very frequently) in the branch "opt". The API functions were moved from z3_api.h to z3_interp.h. It is unclear whether the code will stay in this place or not.

The documentation is for the master branch of Z3, newer features are available in the unstable branch, which will become the new master soon.

This release happened yesterday (v4.3.2). The master branch now contains the interpolation API as well. – Christoph Wintersteiger Oct 25 '14 at 16:11
