Rapid responses are electronic letters to the editor. They enable our users to debate issues raised in articles published on thebmj.com. Although a selection of rapid responses will be included online and in print as readers' letters, their first appearance online means that they are published articles. If you need the url (web address) of an individual response, perhaps for citation purposes, simply click on the response headline and copy the url from the browser window. Letters are indexed in PubMed.
I would stick with flow chart if I were you. According to the Concise
Dictionary (admittedly not as much fun as delving into Arabic history) an
algorithm is a "process or set of rules to be followed in calculations or
problem-solving operations, especially by a computer"; a flow chart is a
diagram of actions making up a complex system, or a graphical
of a computer program. So the algorithm is the process but the flow chart
representation. And, like you, I prefer short words.
