Along each of 126 evolutionary histories the line-of-descent (LOD) of the fittest agent after 60,000th generation is traced back. Absence of cross-over in the evolution confirms that only one agent lies on LOD in every generation. SMMI is calculated every generation for the agent along the LOD. The data is color-mapped according to the number of generation the agent belongs to. The magenta star at correspond to SMMI of 1.08 bits for Einstein - an optimally designed, rather than evolved, network that still retains some stochasticity. Note that SSMI is bounded from above by 2 bits.
