Hi Hélène, It's a custom algorithm developed by Warren DeLano. Some of the details are discussed in this post: https://sourceforge.net/p/pymol/mailman/message/7561993/
The implementation is in SelectorAssignSS in layer3/Selector.cpp: https://sourceforge.net/p/pymol/code/HEAD/tree/trunk/pymol/layer3/Selector.cpp#l1885 Hope that helps.
