Finding optimal, stable matchings for HR is of great importance as it solves real-world problems. For instance, the National Resident Matching Program uses an algorithm like the one presented here to assign medical students in the US to hospitals. An algorithm which solves HR was originally presented in but further work was done to …

The matching is optimal in the sense that that sum of the absolute pairwise distances in the matched … 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… ready mixed self levelling screed how to take care of betta fish in a bowl
