WebJan 1, 2016 · The spatial matching using this criterion is called optimal matching (Munkres, 1957 ). Another criterion is to minimize the maximum cost of any match in the matching. The spatial matching using this criterion is called bottleneck matching (Gross, 1959 ). Webcommon matching method, although there is no consistency in the caliper width that is used [3, 4]. Furthermore, one can consider matching with or without replacement. Matching with replacement and optimal matching appear to be used infrequently in the applied literature.
