Efficient sampling-based bottleneck pathfinding over cost maps

Kiril Solovey, Dan Halperin

We introduce a simple yet effective sampling-based planner that is tailored for bottleneck pathfinding: Given an implicitly-defined cost map $\mathcal{M}:\mathbb{R}^d\rightarrow \m…

Collision detection or nearest-neighbor search? On the computational bottleneck in sampling-based motion planning

Michal Kleinbort, Oren Salzman, Dan Halperin

The complexity of nearest-neighbor search dominates the asymptotic running time of many sampling-based motion-planning algorithms. However, collision detection is often considered…

Optimal randomized incremental construction for guaranteed logarithmic planar point location

Michael Hemmer, Michal Kleinbort, Dan Halperin

Given a planar map of segments in which we wish to efficiently locate points, we present the first randomized incremental construction of the well-known trapezoidal-map search-…

Efficient high-quality motion planning by fast all-pairs r-nearest-neighbors

Michal Kleinbort, Oren Salzman, Dan Halperin

Sampling-based motion-planning algorithms typically rely on nearest-neighbor (NN) queries when constructing a roadmap. Recent results suggest that in various settings NN queries ma…

On the hardness of unlabeled multi-robot motion planning

Kiril Solovey, Dan Halperin

In unlabeled multi-robot motion planning several interchangeable robots operate in a common workspace. The goal is to move the robots to a set of target positions such that each po…

The Offset Filtration of Convex Objects

Dan Halperin, Michael Kerber, Doron Shaharabani

We consider offsets of a union of convex objects. We aim for a filtration, a sequence of nested cell complexes, that captures the topological evolution of the offsets for increasin…
