Summary. It is shown how the theory of branching processes can be applied in the analysis of the expected height of random trees. In particular, we will study the height of random binary search trees, random kd trees, quadtrees and unionend trees under various models of randomization. For example, for the random binary search tree constructed from a random permutation of 1,..., n, it is shown that H„/(c log (n)) tends to 1 in probability and in the mean as n oo, where H „ is the height of the tree, and c =4.31107... is a solution of the equation c log (2e / = 1. In addition, we ~c ~ show that H „clog (n) = O (/log (n) loglog (n)) in probability.

In this paper, we consider stochastic linear systems under the maxplus algebra. For such a system, the states are governed by the recursive equation X n = A X n01 8 U n with the initial condition X 0 = x 0 . By transforming the linear system under the maxplus algebra into a sublinear system under the usual algebra, we establish various exponential upper bounds for the tail distributions of the states X n under the i.i.d. assumption on f(A n ; U n ); n 1g and a couple of regularity conditions on (A 1 ; U 1 ) and the initial condition x 0 . These upper bounds are related to the spectral radius (or the PerronFrobenius eigenvalue) of the nonnegative matrix in which each element is the moment generating function of the corresponding element in the statefeedback matrix A 1 . In particular, we have Kingman's upper bound for GI/GI/1 queue when the system is onedimensional. We also show that some of these upper bounds can be achieved if A 1 is lower triangular. These bounds are applied to some commonly used systems to derive new results or strengthen known results.

New results on the speed of spread of the onedimensional spatial branching process are described. Generalizations to the multitype case and to d dimensions are discussed. The relationship of the results with deterministic theory is also indicated. Finally the theory developed is used to reprove smoothly (and improve slightly) results on certain datastorage algorithms arising in computer science.

Given a branching random walk, let Mn be the minimum position of any member of the nth generation. We calculate EMn to within O(1) and prove exponential tail bounds for P{Mn −EMn > x}, under quite general conditions on the branching random walk. In particular, together with work by Bramson [Z. Wahrsch. Verw. Gebiete 45 (1978) 89–108], our results fully characterize the possible behavior of EMn when the branching random walk has bounded branching and step size. 1. Introduction. The

Consider the family tree of an agedependent branching process, where the branches have costs corresponding to birth times. The firstbirth problem of Hammersley (1974) then concerns the cost of an optimal (cheapest) node at depth n. Suppose that we must explore the tree so as to find an optimal or nearly optimal node at depth n. We now have a suitable model for analysing the behaviour of tree search algorithms, and we may extend the investigations of Karp and Pearl (1983).
