Information: There is some concern in the chess community that some versions of Houdini may contain substantial parts of Stockfish code. These concerns have not been tested in a court of law, or reviewed by court-appointed independent experts. Please refer to the about page for comments on the inclusion of engines for testing.
This is one of the 5 Houdini versions we tested: Compare them!
