Optimal Parallel Algorithms for Convex Hulls in 2D and 3D under Noisy Primitive Operations

Michael T. Goodrich, Vinesh Sridhar

In the noisy primitives model, each primitive comparison performed by an algorithm, e.g., testing whether one value is greater than another, returns the incorrect answer with rando…

Exact Learning of Weighted Graphs Using Composite Queries

Michael T. Goodrich, Songyu Liu, Ioannis Panageas

In this paper, we study the exact learning problem for weighted graphs, where we are given the vertex set, , of a weighted graph, , but we are not given . The prob…

Parallel Joinable B-Trees in the Fork-Join I/O Model

Michael Goodrich, Yan Gu, Ryuto Kitagawa +1

Balanced search trees are widely used in computer science to efficiently maintain dynamic ordered data. To support efficient set operations (e.g., union, intersection, difference)…

Computational Geometry with Probabilistically Noisy Primitive Operations

David Eppstein, Michael T. Goodrich, Vinesh Sridhar

Much prior work has been done on designing computational geometry algorithms that handle input degeneracies, data imprecision, and arithmetic round-off errors. We take a new approa…

Quantum Combine and Conquer and Its Applications to Sublinear Quantum Convex Hull and Maxima Set Construction

Shion Fukuzawa, Michael T. Goodrich, Sandy Irani

We introduce a quantum algorithm design paradigm called combine and conquer, which is a quantum version of the "marriage-before-conquest" technique of Kirkpatrick and Seidel. In a…

Dynamic Accountable Storage: An Efficient Protocol for Real-time Cloud Storage Auditing

Michael T. Goodrich, Ryuto Kitagawa, Vinesh Sridhar

Ateniese, Goodrich, Lekakis, Papamanthou, Paraskevas, and Tamassia introduced the Accountable Storage protocol, which is a way for a client to outsource their data to a cloud stora…
