Saddles and Barrier in Landscapes of Generalized Search Operators
Barrier trees are a convenient way of representing the structure of complex combinatorial landscapes over graphs. Here we generalize the concept of barrier trees to landscapes deļ...

Complexity of Stochastic Branch and Bound Methods for Belief Tree Search in Bayesian Reinforcement Learning
There has been a lot of recent work on Bayesian methods for reinforcement learning exhibiting near-optimal online performance. The main obstacle facing such methods is that in most...

Searching Trees: An Essay
We are reviewing recent advances in the run time analysis of search tree algorithms, including indications to open problems. In doing so, we also try to cover the historical dimens...

Upper Bounds for Maximally Greedy Binary Search Trees
At SODA 2009, Demaine et al. presented a novel connection between binary search trees (BSTs) and subsets of points on the plane. This connection was independently discovered by Der...

Scapegoat Trees
We present an algorithm for maintaining binary search trees. The amortized complexity per INSERT or DELETE is O(log n) while the worst-case cost of a SEARCH is O(log n). Scapegoat...
