In various fields of physics and astronomy, access to experimental facilitiesor to telescopes is becoming more and more competitive and limited. It becomestherefore important to optimize the type of measurements and their schedulingto reach a given scientific objective and to increase the chances of success ofa scientific project. In this communication, extending the work of Ford (2008)and of Loredo et al. (2012), we present an efficient adaptive scheduling toolaimed at prioritzing measurements in order to reach a scientific goal. Thealgorithm, based on the Fisher matrix, can be applied to a wide class ofmeasurements. We present this algorithm in detail and discuss somepracticalities such as systematic errors or measurements losses due tocontigencies (such as weather, experimental failure, ...). As an illustration,we consider measurements of the short-period star S0-2 in our Galactic Center.We show that the radial velocity measurements at the two turning points of theradial velocity curve are more powerful for detecting the gravitationalredshift than measurements at the maximal relativistic signal. We alsoexplicitly present the methodology that was used to plan measurements in orderto detect the relativistic redshift considering systematics and possiblemeasurements losses. For the future, we identify the astrometric turning pointsto be highly sensitive to the relativistic advance of the periastron. Finally,we also identify measurements particularly sensitive to the distance to ourGalactic Center: the radial velocities around periastron and the astrometricmeasurements just before closest approach and at the maximal right ascensionastrometric turning point.
