Nice introduction. 1. Please always make closed and open interval explicit on all code examples. "Detecting overlap" is ambiguous and open intervals have no given solution in the article, if I'm not mistaken. 2. How do you define the empty interval on floating point numbers? How do you define an open interval on floating point numbers? Number representation, input range etc can be very important. Disclosure: Did some stupidly crazy time series eval for OCPP1.6 and OCPP2.01 charging profiles.
