Closed access Metadata (CSL-JSON)
DOI 10.1137/1.9781611975345.ch2
Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

In this chapter we pause in our development of core-chasing algorithms to describe Francis's implicitly shifted QR (bulge-chasing) algorithm and explain why it works. This material overlaps significantly with [74] and [73, Sections 6.1–6.3]. We will draw extensively from [74].
