Figure 7From: PQR sort: using PQR trees for binary matrix reorganizationExecution time (in milliseconds) for Sugiyama, 2D sort, and PQR sort. (a) Block experiment, matrix size 100 × 100. (b) Block experiment, matrix size 1000 × 1000. (c) Rectnoise experiment, matrix size 100 × 100. (d) Rectnoise experiment, matrix size 1000 × 1000. Time axis in logarithmic scale. The error bars stand for a confidence interval of 99.7%.Back to article page
