Abstract:Abstract. We study a class of adaptive multi-digit tries, in which the numbers of digits rn processed by nodes with n incoming strings are such that, in memoryless model (with n → ∞):where η is an algorithm-specific constant. Examples of known data structures from this class include LC-tries (Andersson and Nilsson, 1993), "relaxed" LC-tries (Nilsson and Tikkanen, 1998), tries with logarithmic selection of degrees of nodes, etc. We show, that the average depth D n of such tries in asymmetric memoryless model ha… Show more
