Caviness (editor), EUROCAL '85, European Conference on Computer Algebra, Linz, Proceedings, Volume 2, Springer, LNCS 204, page 279, In a quadratic field Q (√), D a squarefree integer, with class number 1 any algebraic integer can be decomposed uniquely into primes but for only 21 domains Euclidean algorithms are known. We prove that for D<-19 even remainder sequences with possibly nondecreasing norms cannot determine the GCD of arbitrary inputs.

Rolim, Emo Welzl (editors), Automata, Languages and Programming: 27th International Colloquium, Proceedings, Springer, LNCS 1853, page 373, In this paper, we provide new analyses that characterize the precise average bit-complexity of a class of Euclidean algorithms. We consider here five algorithms that are all classical variations of the Euclidean algorithm and are called Classical (G), By-Excess (L), Centered (K), Subtractive (T) and Binary (B).
