    Streaming Similarity Search over One Billion Tweets Using Parallel Locality-Sensitive Hashing by Sundaram, Narayanan, Turmukhametova, Aizana Z., Satish, Nadathur, Mostak, Todd, Indyk, Piotr, Madden, Samuel R., Dubey, Pradeep

    Published 2014
    “…One popular algorithm for similarity search, especially for high dimensional data (where spatial indexes like kd-trees do not perform well) is Locality Sensitive Hashing (LSH), an approximation algorithm for finding similar objects. In this paper, we describe a new variant of LSH, called Parallel LSH (PLSH) designed to be extremely efficient, capable of scaling out on multiple nodes and multiple cores, and which supports high-throughput streaming of new data. …”

    Distributed Task Allocation Algorithms for Multi-Agent Systems With Very Low Communication by Akshay Bapat, Bharath Reddy Bora, Jeffrey W. Herrmann, Shapour Azarm, Huan Xu, Michael W. Otte

    Published 2022-01-01
    “…We present two task allocation algorithms that assume communication may not happen, but that benefit whenever communications are successful. (1) The Spatial Division Playbook Algorithm divides task among agents based on an area decomposition. (2) The Traveling Salesman Playbook Algorithm considers mission travel distance by leveraging Christofides&#x2019; 3/2 approximation algorithm. These algorithms have task completion runtime complexity of <inline-formula> <tex-math notation="LaTeX">$O(m \log m)$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$O(m^{3})$ </tex-math></inline-formula>, respectively, where <inline-formula> <tex-math notation="LaTeX">$m$ </tex-math></inline-formula> refers to the total number of tasks. …”
