    Abstract : This study aims to construct an efficient heuristic, referred to as RA, for a riskaverse Markovian multi-armed bandit problem (MAB) with multiple plays. The RA incorporates risk-aversion and multiple plays by modifying the Gittins index strategy. READ MORE

  4. 3. Comparing the Locality Preservation of Z-order Curves and Hilbert Curves

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Alex Nordin; Adam Telles; [2023-08-03]
    Keywords : space-filling curve; software engineering; software testing;

    Abstract : Developing and testing software in the automotive industry and in the research of autonomous vehicles requires the costly querying of multidimensional data recorded from such a vehicle’s various sensors. Through encoding such data using space filling curves, faster queries could be achieved by reducing multiple dimensions into a singular dimension, while exploiting the patterns that emerge in the one-dimensional representation to still get accurate search results.
