Relations of balls with urns where each ball has been moved (N = 500, K = 250): the a periodic and b phase-modulated periodic connecting systems. The plots in grayscale denote the frequencies of the urns where each ball has been moved for 10,000 iterations from the 4.99-millionth to the 5-millionth iteration. The rows (balls) and columns (urns) are sorted in ascending order by the score calculated by correspondence analysis (see "Methods")
