Kangaroo the sniffing gains much information from smell cues. This behaviour enforces social cohesion without consequent aggression. During mutual sniffing, if one kangaroo is smaller, it will hold its body closer to the ground and its head will quiver, which serves as a possible form of submission. Greetings between males and females are common, with larger males being the most involved in meeting females. Most other non-antagonistic behaviour occurs between mothers and their young. Mother and young reinforce their bond though grooming. A mother will groom her young during or after it is suckling. A joey will nuzzle its mother's pouch
Pollard's kangaroo algorithm the sequence formula_31, since it starts from the position b to the right of x. Accordingly, the longer stroke corresponds to the sequence formula_27, which "collides with" the first sequence (just like the strokes of a lambda intersect) and then follows it subsequently. Pollard has expressed a preference for the name "kangaroo algorithm", as this avoids confusion with some parallel versions of his rho algorithm, which have also been called "lambda algorithms". Pollard's kangaroo algorithm In computational number theory and computational algebra, Pollard's kangaroo algorithm (also Pollard's lambda algorithm, see Naming below) is an algorithm for solving the discrete logarithm
