N-body problem integration (N=4: one star, one heavy planet and one light planet with a satellite) computed with 2 slightly different sets of initial conditions (sensitivity to initial conditions) [Intégration du problème des N-corps (N=4: une étoile, une planète lourde et une planète légère avec un satellite) calculé avec 2 jeux de conditions initiales très légèrement différentes (sensibilité aux conditions initiales)].




The same program is used 2 times with 2 slightly different sets of initial conditions, moving 1 meter the heaviest planet.


There is no difference between this sensitivity to initial conditions N-body problem integration (N=4: one star, one heavy planet and one light planet with a satellite)computed with 2 slightly different sets of initial conditions (sensitivity to initial conditions) and the sensitivity to rounding-off errors N-body problem integration (N=4: one star, one heavy planet and one light planet with a satellite)computed with 2 different optimization options on the same computer (sensitivity to rounding-off errors) .


(the computations correspond to a physical duration of 88 terrestrial years)
