Evolutionary structural optimisation (ESO) using a bidirectional algorithm. (English) Zbl 0938.74056
From the summary: We combine the basic ESO with the additive evolutionary structural optimisation (AESO) to produce bidirectional ESO, whereby material can be added and can be removed. It is shown that this provides the same results as the traditional ESO. This has two benefits, it validates the whole ESO concept, and there is a significant time saving, since the structure grows from a small initial one rather than contracting from a sometimes huge initial one where 90 per cent of the material gets removed over many hundreds of finite element analysis evolutionary cycles.
