WebOur main result is an online algorithm for nding an NPO matching that has a competitive ratio of O( p n). By proving a matching lower bound, we show that our algorithm is asymptotically optimal. For necessary rank-maximality, we design e cient algorithms for checking whether a given matching is NRM. Optimal matching is a sequence analysis method used in social science, to assess the dissimilarity of ordered arrays of tokens that usually represent a time-ordered sequence of socio-economic states two individuals have experienced. Once such distances have been calculated for a set of observations (e.g. individuals in a cohort) classical tools (such as cluster analysis) can be used. The method was tailored to social sciences from a technique originally introduced to study mole…
