Mathematics Results

Average Percentage Accurate: 68.9% → 94.1%
Time: 23.9min
Bad Runs: 4/53
Speedup: 4.6×

Output vs Input Accuracy

Each point represents a Herbie run below. Its horizontal position shows initial accuracy, and vertical position shows final accuracy. Points above the line are improved by Herbie.

Accuracy vs Speed

A joint speed-accuracy pareto curve. Accuracy is on the vertical axis, speed is on the horizontal axis. Up and to the right is better. The initial program is shown by the red square.
