Random dense packed spheres are a widely applicable model to simulate structures. There are different approaches to get dense packed systems. One of them is the so called force biased algorithm. A system of spheres is densified by stepwise rearrangement of sphere centres and recalculation of diameters. Some ways to optimize this algorithm are explained, especially the optimization of the virtual interaction forces between spheres during the packing process. It is demonstrated how systems with arbitrary size distributions can be optimized under different constraints.
