• Hill Climbing, Backpropagation and NEAT on the Same XOR Problem

  October 10, 2026

  I expected backpropagation to learn XOR with the least work. At learning rate 0.5 it needed 9,268 to 11,124 network runs where a random-nudge hill climber needed 1,512 to 1,648. Only on a two-output full adder did it win, needing about a third of the hill climber's work.
