series of box plots of the minimum loss per particle. The horizontal black line marks our quality threshold of 0.002 and in general we observe that assembly for smaller targets is more robust than assembly of larger targets, as expected. Figure examines the number of steps per cycle. A larger number of steps per cycle gives the particles more time to adapt to the gradually increasing restraint forces that encourage assembly, however they also increase the computational cost of the simulation. As all simulations here use 2 fs timesteps and 150 cycles, the total length of the trajectories ranges from 30 ps (for 100 steps/cycle) to 150 ps (for 500 steps/cycle). Generally, we observe an increase in the quality of the assembly with increasing steps per cycle, with 500 steps (green bars) showing median values that are at or below our quality threshold for all of the cases examined here.
