We introduce cloning transformations that take N identical replicas of a pure state in any dimension as input and yield a collection of clones with nonidentical fidelities. As an example, if the clones are partitioned into a set of M-A clones with fidelity F-A and another set of M-B clones with fidelity F-B, the trade-off between these fidelities is analyzed, and particular cases of optimal N -> M-A+M-B cloning machines are exhibited. We also present an optimal 1 -> 1+1+1 cloning machine, which is an example of a tripartite fully asymmetric cloner. Finally, it is shown how these cloning machines can be optically realized."@en . .
