Representation is a crucial concept in classical computing. Unconventional computational devices pose a series of challenges to representational issues, including unary analogue encodings, the representation of inputs and outputs, and sometimes the inaccessibility of internal states. Of particular interest are successive representational adaptation and refinement in relation to natural information processes, both during biological evolution and in evolving material and smart microparticle systems. Some examples are discussed in this chapter.
