In Part I, so-called ‘optimal plastic design’ of multi-load trusses is reviewed, which is based on ultimate (limit or collapse) load principles and requires only statical admissibility of the solution. However, …

Weblatter also gives optimality conditions for ‘vanishing’ members (of zero cross-sectional area). In other words, optimal layout theory starts off with a ‘ground structure’ of all potential members, and selects the optimal ones (of non-zero cross-sectional area) out of these.
