Figure 8. AEP encoding scheme-Selecting Operations for Assembler Encoding

<p>Each population delegates exactly one representative to each AEP.<br> In the beginning, AEPs have only one operation and a sequence of data. Both the operation<br> and data come from two different populations. Further populations including operations are<br> successively added if AEPs cannot accomplish progress in performance over the assumed<br> number of co-evolutionary cycles (we use term &ldquo;co-evolutionary cycle&rdquo; to differ it from the<br> evolutionary generation that takes place inside a single population with operations and data).</p>
