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.
This paper is devoted to the description of structure of evolution algebras of "chicken" population (EACP). Such an algebra is determined by a rectangular matrix of structural constants. Using the Jordan form of the matrix of structural constants we obtain a simple description of complex EACP. We give the classification of three-dimensional complex EACP. Moreover, some (n + 1)-dimensional EACP are described.
