Abstract: According to an aspect, a method for providing a minimal explanation to a set of unsatisfiable constraints involves retrieving a minimal subset of constraints that remain together unsatisfiable. The method includes iterating over a list of n constraints, and building a minimal explanation to a set of unsatisfiable constraints by determining which constraint to add to the set of unsatisfiable constraints. Building includes accelerating by removing an increasing number of constraints until removed further constraints makes the set of constraints satisfiable. A dichotomic search is performed on the removed further constraints. The average observed distance is identified between successive constraints in the set of unsatisfiable constraints. A plurality of 2k further constraints located in the list of constraints is removed at the average observed distance from the most recently added constraint. Testing whether a current selected subset is unsatisfiable is performed for the first log2(n) added constraints.

Abstract: On an aircraft it is proposed that the orientation (pitch and roll attitudes and heading) of a support structure (10), such as the structure supporting the optical head of a head-up control system, be regulated by means of an inertial unit (16). The said unit is firstly placed on its previously regulated rack (14) in the hold of the aircraft and the three orientation parameters are measured. The inertial unit (16) is then placed on an intermediate support (26) fixed to the support structure (10) and the orientation parameters are again measured. Following the comparison of the two measurements, the orientation of the support structure (10) is corrected so as to cancel out their differences.
