    Sammanfattning : In this thesis, we explore two distinct topics. The first part of the thesis delves into efficient exploration in  multi-task bandit models and model-free exploration in large Markov decision processes (MDPs). LÄS MER

  7. 5. Controlling Timing Channels in Multithreaded Programs

    Författare :Alejandro Russo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The problem of controlling information flow in multithreaded programs remains an important open challenge. A major difficulty fortracking information flow in concurrent programs is due to the internal timing covert channel. LÄS MER
