arXiv, 2019 In the coupon collector problem with $n$ items, the collector needs a random number of tries $T_n\simeq n\ln n$ to complete the collection. Also, after $nt$ tries, the collector has secured approximately a fraction $\zeta_\infty(t)=1-e^{-t}$ of the complete collection, so we call $\zeta_\infty$ the (asymptotic) \emph{completion curve}.

Conference Companion of the 2nd International Conference on Art, Science, and Engineering of Programming, 2018 Observing and modifying object-oriented programs often means interacting with objects. At runtime, it can be a complex task to identify those objects due to the live state of the program. Some objects may exist for only a very limited period of time, others can be hardly reachable because they are never stored in variables.
