  Different advanced bridge function closures are utilized to investigate the
structural and thermodynamic properties of dense Yukawa one-component plasma
liquids within the framework of integral equation theory. The isomorph-based
empirically modified hypernetted-chain, the variational modified
hypernetted-chain, the Rogers-Young and the Ballone-Pastore-Galli-Gazzillo
approaches are compared at the level of thermodynamic properties, radial
distribution functions and bridge functions. The comparison, based on accuracy
and computational speed, concludes that the two modified hypernetted-chain
approaches are superior and singles out the isomorph-based variant as the most
promising alternative to computer simulations of structural properties of dense
Yukawa liquids. The possibility of further improvement through artificial
cross-over to exact asymptotic limits is studied.
