....though these have been considerably over hyped they include many new useful techniques and metaphors. They are not, however, based on any coherent complexity theory . Key practitioners in these fields recognise this and have frequently exhorted, anticipated and worked towards such a theory (e.g. [2, 12]) but at the moment there is no such body of general theory which has a useful analytical meaning outside individual component fields. What these widely differing areas do share is a tendency to: use newer formal techniques (logics, automata, topological models, etc. deal with systems ....

....of modelling (principally the language of modelling) and obscures the interplay of complexity, specificity and the error involved. 5 Order and Disorder It has been frequently asserted that complexity lies somewhere between order and disorder [6] what is sometimes called the edge of chaos [7]) Thus in figure 1 below many people judge that the middle pattern is more complex than the other two. Figure 1: Three patterns (after Grassberger [6] As a result of this idea graphs like figure 2 have dominated the literature about complexity in physics. However, as I shall argue, for such a ....

....that have interactions between K 1 or fewer bits. Several upper bounds on the extent of the coverage by NK Landscapes are created based on theory developed in the paper. 1 INTRODUCTION A very useful and popular experimental model for correlated landscapes is Stuart Kauffman s NKLandscapes [2, 3]. An NK Landscape is a function f : B R where K is the number of bits in the chromosome that epistatically interact with each bit. One of the nice features of NK Landscapes is that K acts as a tunable ruggedness control. When K = 0, the landscape is the average of the sum of the weights ....

....be used interchangeably with binary for representing strings in B with b 0 being the least significant bit. A hyperplane or schema is denoted in the usual way. For example, hyperplane h for strings in B might be 1101 . ffl Let [i] denote extracting the i bit. So if x =1111011 then x[2] = 0. x[i; j] denotes extracting and right justifying the bits i through j. For example x[2; 5] 1110. ffl The bit count function bc(i) returns the number of 1 s in i. For example bc(001011) 3 and bc(15) 4. ffl i j where i; j 2 B reads as i is contained in j. That is wherever there is a ....

....(Kargupta Goldberg, 1994) A different type of GA difficulty is epistasis where random and highly ordered epistatic interactions are distinguished. In the first kind of epistasis a linkage between two genes has a random influence on the fitness like it is defined in the NK landscape problem by Kauffman (1993). This work focuses on the second type of epistasis where there are interdependencies between the dimensions of the search space on the phenotype level. In this connection, Salomon (1996) generated epistatic problems by rotating standard benchmark functions which are mostly decomposable without ....

....does not occur in EUZONE. In other work (Downing, 1997) genetic algorithms are used to show that temporal ideal free distributions are the natural consequence of Neo Darwinian evolution in resource limited environments. Our project is related to research into the emergence of autocatalytic sets (Kauffman, 1993), metabolic systems (Bagley and Farmer, 1992) and hypercycles (Boerlijst and Hogeweg, 1992) except that we focus on (a) interaction pathways involving both organisms and chemicals, and (b) the self organized regulation of the environment by the evolving biota. In general, a whole host of alife ....

....ways in which genotype, coupled with molecular environments through feedback networks of chemical reactions, aggregates up into phenotype, during the process of development. Phenotype is assumed, but not explained, in current natural selection theory. See Buss (1987) Fontana and Buss (1994) Kauffman (1993), Goodwin (1994) and Newman (1994) 3 place tends to discover a cornucopia of organizational forms, well beyond the range of our usual Americanist vision. Arguably, all these forms are adapted to a local environment which has selected them on some criteria of performance . But the sheer ....

....that also recognises self organisation as another major component in biological evolution, thus stressing the necessity of going beyond the predominant view that natural selection provides. At least from this macro perspective this view is very similar to the one Kauffman has put forward in [Kauffman 1991], which was epitomized by his monograph [Kauffman 1993] In the context of the latter topic, it is relevant to mention the biological notion of exaptation, a term proposed in [Gould and Vrba 1982] to refer to structures whose function did not arise as a consequence of progressive adaptations via ....

....output, an analytical approach to product innovation requires the development of new models and concepts. We develop a system s perspective on product development, which is derived from more general computational models of complex systems as these have been developed in evolutionary biology (Kauffman 1993; Altenberg 1997) Using this model, we can understand products as being made up by elements that interrelate in their functioning in complex ways. The important insight that is derived from an understanding of products as complex systems holds that product innovation in one part of the system ....

....of product development in turn informs us regarding the patterns to expect in empirical data analysis regarding the product and price differentiation in a population of product models offered on a market. The paper is organised as follows. Section 2 describes a conceptual model, which is based on Kauffman s (1993) NK model of complex systems and which is generalised using (1997) model of complex systems. Section 3 provides an analysis of complex patterns in variety 1 This drawback of output statistics is also emphasised in discussions on the impact of ICT on economic growth and welfare. In these debates, ....
