    "abstract": "We present a method (the Aufbau/Abbau method) for optimizing the structure of\na whole series of clusters without making any assumptions on the structure.\nSubsequently, the method is combined with the embedded-atom method in\ndetermining the structure of the two energetically lowest isomers of Ni_N\nclusters with N up to 150. Finally, various analytical descriptors are\nintroduced that are used in studying the overall shape of the clusters, their\nstructure and stability, and possible growth and dissociation processes.",
