Accelerating Diffusion Models with Parallel Sampling: Inference at Sub-Linear Time Complexity

Neural Information Processing Systems
Diffusion models have become a leading method for generative modeling of both image and scientific data. As these models are costly to train and evaluate, reducing the inference cost for diffusion models remains a major goal.

The Time Complexity of Consensus Under Oblivious Message Adversaries

Information Technology Convergence and Services
We study the problem of solving consensus in synchronous directed dynamic networks, in which communication is controlled by an oblivious message adversary that picks the communication graph to be used in a round from a fixed set of graphs $$\textbf{D}$$

Challenging the Time Complexity of Exact Subgraph Isomorphism for Huge and Dense Graphs with VF3

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2018
Graph matching is essential in several fields that use structured information, such as biology, chemistry, social networks, knowledge management, document analysis and others.

Influence maximization: near-optimal time complexity meets practical efficiency

SIGMOD Conference, 2014
Given a social network G and a constant $k$, the influence maximization problem asks for k nodes in G that (directly and indirectly) influence the largest number of nodes under a pre-defined diffusion model.

Optimal Time-Complexity Speed Planning for Robot Manipulators

IEEE Transactions on robotics, 2018
In this paper, we consider the speed planning problem for a robotic manipulator. In particular, we present an algorithm for finding the time-optimal speed law along an assigned path that satisfies velocity and acceleration constraints and respects the ...

Verifying Asymptotic Time Complexity of Imperative Programs in Isabelle

International Joint Conference on Automated Reasoning, 2018
We present a framework in Isabelle for verifying asymptotic time complexity of imperative programs. We build upon an extension of Imperative HOL and its separation logic to include running time.

Complexity and the Arrow of Time [PDF]

open access: possible, 2013
There is a widespread assumption that the universe in general, and life in particular, is 'getting more complex with time'. This book brings together a wide range of experts in science, philosophy and theology and unveils their joint effort in exploring this idea.

Sparse Semidefinite Programs with Near-Linear Time Complexity

IEEE Conference on Decision and Control, 2017
Some of the strongest polynomial-time relaxations to NP-hard combinatorial optimization problems are semidefinite programs (SDPs), but their solution complexity of up to O(n6.5 L) time and O(n4) memory for $L$ accurate digits limits their use in all but ...

Transcription of chromatin: these are complex times

Current Opinion in Genetics & Development, 1998
Transcription of chromatin-packaged genes involves highly regulated changes in nucleosomal structure that control DNA accessibility. Two systems that facilitate these changes are ATP-dependent chromatin remodeling complexes and enzymatic complexes which control histone acetylation and deacetylation.

Time, Complexity and the Global

2002
This chapter presumes that a new kind of social science ‘paradigm’, that of globalization, is currently being developed and reproduced. I examine some connections between this emergent globalization paradigm and another paradigm, that of complexity. The latter is also emerging as a contending new paradigm for the social sciences, having already been ...
