Web29 de ago. de 2024 · In the paper “Online Matching with Stochastic Rewards: Optimal Competitive Ratio via Path-Based Formulation,” the authors develop a novel algorithm analysis approach to address stochastic elements in online matching. The approach leads to several new ...The problem of online matching with stochastic rewards is a … Web8 de dez. de 2024 · In particular, we follow the approach of Hosseini et al. and investigate the elicitation of necessarily Pareto optimal (NPO) and necessarily rank-maximal (NRM) matchings. Most importantly, we answer their open question and give an online algorithm for eliciting an NRM matching in the next-best query model which is 3/2-competitive, i.e., …

WebOptimal 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 … 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.
