  Recent emerging interest in experiments of single-polymer dynamics urge
computational physicists to revive their understandings, particularly in the
nonequilibrium context. Here we briefly discuss the currently evolving
approaches of investigating the evolution dynamics of homopolymer collapse in
computer simulations. Primary focus of these approaches is to understand
various dynamic scaling laws related to coarsening and aging during the
collapse in space dimension $d=3$, using tools popular in nonequilibrium
coarsening dynamics of particle or spin systems. In addition to providing an
overview of those results, we also present new preliminary data for $d=2$.
