Fig. 3.

Time series data from a typical simulation run for a population size of N = 50 and a total of 10⁷ attempted mutations (only first 10⁶ steps shown for clarity) for evolution of solutions for the patterning problem. The parameter t represents the number of attempted mutations. Each mutation is separated by an average of 1/Nμ∣G∣ generations. (A) Fitness F versus time (gray) and steepness of morphogen gradient αL versus time (red). (B) Time series of binding energies E_ij of ith protein to jth binding site of regulatory region of T. (C) Time series of glue energies δE_ii′, between the ith and i′th protein.
