Webwarping window (parameter) tuned was a strong TSC baseline for more than a decade [22]. Many measures with di erent properties and alignment strategies were proposed [4,17,26,38,48] but none of them were able to signi cantly outperform DTW. The Ensemble of Elastic Distances (EE) was the rst algorithm that was signi cantly more accurate than NN ...

If the third run still shows a deviation or when random time warps are detected the test terminally fails.
