Using the basin-hopping Monte Carlo minimization approach we report theglobal minima for aluminium, gold and platinum metal clusters modelled by theVoter-Chen version of the embedded-atom model potential containing up to 80atoms. The virtue of the Voter-Chen potentials is that they are derived byfitting to experimental data of both diatomic molecules and bulk metalssimultaneously. Therefore, it may be more appropriate for a wide range of thesize of the clusters. This is important since almost all properties of thesmall clusters are size dependent. The results show that the global minima ofthe Al, Au and Pt clusters have structures based on either octahedral,decahedral, icosahedral or a mixture of decahedral and icosahedral packing. The54-atom icosahedron without a central atom is found to be more stable than the55-atom complete icosahedron for all of the elements considered in this work.The most of the Al global minima are identified as some fcc structures and manyof the Au global minima are found to be some low symmetric structures, whichare both in agreement with the previous experimental studies
