nate the set of alleles of locus i (see section 3.1) and the corresponding representation of A is the specification of the ordered set of alleles which make up the chromosome. For a von Neumann economy (section 3.2) the Vi can designate the possible levels of the ith activity so that the representation of a mixture of activities is simply the corresponding activity vector. Similar considerations apply to each of the remaining illustrations of chapter 3. Clearly, with a given set of l detectors, two structures will be distinguishable only insofar as they have distinct representations. Since, in the present chapter, we are only interested in comparisons let us assume that all structures in are distinguishable (have distinct representations) or, equivalently, that is used to designate distinguishable subsets of the original set of structures. For simplicity in what follows will simply be taken to be the set of representations provided by the detectors (rather than the abstract elements so represented).
