SPOCK

SPOCK (for Stability of Planetary Orbital Configurations Klassifier) is a code to determine whether the orbits of sets of objects around a host will remain stable (i.e., no dramatic changes for on the order of a billion orbits). It uses machine-learning classification techniques rather than the well-known analytical methods or simulation of that number of orbits. By design, its input consists of observation-data commonly gathered by extra-solar planet observations.
