We then proposed the RT-estimator, which is a modification of the classical respondent-driven sampling, making use of the idea of short crawls and super-node.
These two schemes have advantages of their own: the reinforcement learning scheme offers more control on the stability of the sample path with varying error performance, and the modified RDS scheme based on short crawls is simple and has superior performance compared to the classical RDS.
Indeed, if you're more interested in drinking than eating, use this pub as the starting-point for a short pub crawl down Chapel Street into Salford (technically, the Mark Addy is just over the border).
The "heavy, short-lived crawl" of the ageing Lothario swimmer.
The New York hip-hop trio are the Beastie Girls of a new millennium, rapping hilariously and disgustingly on songs like Cameltoe: "I gotta be blunt/ Her spandex biker shorts were crawling up her front".

It dawned on me that some of the bees might have spent the winter under the shrubs, and emerged in perfect time to make the short flight (or crawl) to replenish their energy reserves with nectar.
Nobody spoke but they all watched him walk the short distance to crawl into his tent and in less than 15 minutes I heard him snoring all the way out to the campfire.
These short tours or crawls, which start and return to the seed node set, are independent and can be implemented in a massively parallel way.
(Some invertebrate species, such as sponges, anemones, snails, and clams, have larvae that crawl only short distances).
