Update (August 2017): The KIT group used KeY to verify the JDKвЂ™s dual pivot quicksort implementation used as default sorting algorithm for integer or long arrays. The paper with the complete analysis, and several test programs are available on our website. A closer analysis showed that this was, quite simply, because TimSort was broken and our theoretical considerations finally led us to a path towards finding the bug (interestingly, that bug appears already in the Python implementation). Unfortunately, we werenвЂ™t able to prove its correctness.

TimSort seemed to fit the bill, as it is rather complex and widely used. Reasoning 53(2), 129-139) with a formal verification tool called KeY, we were looking for a new challenge. After we had successfully verified Counting and Radix sort implementations in Java ( J. Given the popularity of these platforms this means that the number of computers, cloud services and mobile phones that use TimSort for sorting is well into the billions.ДЇast forward to 2015. TimSort is today used as the default sorting algorithm for Android SDK, SunвЂ™s JDK and OpenJDK. TimSort was first developed for Python, but later ported to Java (where it appears as and ) by Joshua Bloch (the designer of Java Collections who also pointed out that most binary search algorithms were broken). It is a clever combination of ideas from merge sort and insertion sort, and designed to perform well on real world data.

Tim Peters developed the Timsort hybrid sorting algorithm in 2002.
