      abstract     = {A method to study isochoric compression to mass densities
                      relevant for direct-drive fast ignition schemes is
                      presented. The method is based on the combination of
                      one-dimensional radiation-hydrodynamic simulations using the
                      code MULTI-IFE [Ramis and Meyer-ter Vehn, Comput. Phys.
                      Commun. 203, 226 (2016)] and a particle swarm optimization
                      technique [Kennedy and Eberhart, in Proceedings of ICNN'95 -
                      International Conference on Neural Networks (IEEE, Perth,
                      WA, Australia, 1995), Vol. 4, pp. 1942–1948]. The
                      compression of the fuel is optimized through variations of
                      the incident temporal laser power profiles. Uniform mass
                      density profiles are achieved by using appropriate objective
                      functions that allow comparisons between the fuel assemblies
                      obtained from simulations. Several objective functions were
                      created and evaluated on their merits to yield isochoric
                      compression assembly. Ultimately, such a profile is
                      presented in conjunction with the technique to achieve it. A
                      useful objective function is calculating the deviation of
                      the simulated mass density profile from the ideal uniform
                      mass density profile over a volume of the compressed target
                      up to the radial position of the outgoing shock wave.},
