Evolutionary approach

Shakhnovich and Gutin [26] (see also [28,159,160]) showed that it is possible to design a copolymer in such a way that it will fold into a specific conformation. To do this, they optimized the sequence, using a Monte Carlo method that randomly exchanges monomers within the sequence. In this section, we describe an extension of this approach to design a copolymer sequence that is 

To analyze the stability of the ordered microphases, the simplest incompressible random-phase approximation [132] can be employed. Using this approach, the critical value of the Flory-Huggins parameter, x and the corresponding spinodal temperature, T = l/x can be determined by the condition that the scattering intensity S(q) reaches its maximum value at a nonzero wave vector q. Within the RPA the scattering intensity is given by [132,142]

Evolutionary. The evolutionary approach to network development starts with a good network developed by some alternative means and proceeds to change it into an optimal network from the standpoint of cost. The success of any evolutionary method depends gteatiy on the starting network. Evolutionary methods ate specific to starting network characteristics and ate usually matched with the method used to develop the initial network, eg, TI followed by ED. There ate two extremes for possible starting networks. 

The first is a network that has minimum area but a maximum number of exchangers as proposed by the algorithmic—evolutionary approach (10). The algorithmic part of this method is the development of a minimum area network. The evolutionary part employs a set of rules to modify systematically the initial network. The three rules presented ate heuristic in nature and seek to combine exchangers and stream spHts to reduce network cost. The problem of reducing stream spHts appears difficult to researchers.

In most chemical processes reactors are sequenced by systems that separate the desired products out of their outlet reactor streams and recycle the unconverted reactants back to the reactor system. Despite the fact that process synthesis has been developed into a very active research area, very few systematic procedures have been proposed for the synthesis of reactor/separator/recycle systems. The proposed evolutionary approaches are always based upon a large number of heuristic rules to eliminate the wide variety of choices. Many of these heuristics are actually extensions of results obtained by separately studying the synthesis problem of reactor networks or separator systems, and therefore the potential trade-offs resulting from the coupling of the reactors with the separators have not been investigated.
