EMERGE is a fully automatic and highly flexible program for producing low-weight, low-stress structures, developed by the self-designing structures project at Newcastle and Durham Universities. A brief review of the development and features of existing evolutionary methods is first given before going on to discuss evolutionary material translation (EMT)-the core algorithm embedded within EMERGE-and its relative advantages. Most of the existing work done on automatic evolutionary methods has concentrated upon material removal only, the main drawback of this approach being its inability to find improved structural forms outside a predetermined domain. Three notional problems and one industrial problem are presented. These problems demonstrate the flexibility of EMT to design outside or within the preconceptions of the engineer, to produce improved structures with superior boundaries, and to do so with modelling and computational efficiency.
