The Constrained Molecular Dynamics (CoMD) model is used to describe the properties of nuclear systems near the ground state. A procedure for global optimization of the initial conﬁgurations of the nuclei is developed. In addition, the neutron skins of various nuclear systems are calculated. Finally, the GDR and GMR spectra of medium-mass nuclear systems are studied. The effect of the model parameters to the spectra is explored. We conclude that an increased compressibility of K = 308 MeV results in increased GDR energy and decreased skin, while the total energy and the GMR energy remain almost unaltered.
