Improved Dynami Spatial Approximation Trees

Dynami Spatial Approximation Trees

Fully Dynamic and Memory-Adaptative Spatial Approximation Trees

Hybrid dynamic spatial approximation trees are recently proposed data structures for searching in metric spaces, based on combining the concepts of spatial approximation and pivot based algorithms. These data structures are hybrid schemes, with the full features of dynamic spatial approximation trees and able of using the available memory to improve the query time. It has been shown that they c...

Nonlinear Voter Models: The Transition from Invasion to Coexistence

In nonlinear voter models the transitions between two states depend in a nonlinear manner on the frequen ies of these states in the neighborhood. We investigate the role of these nonlinearities on the global out ome of the dynami s for a homogeneous network where ea h node is onne ted to m = 4 neighbors. The paper unfolds in two dire tions. We rst develop a general sto hasti framework for frequ...
