    Sammanfattning : The introduction of initial margin requirements for non-cleared OTC derivatives has made it possible to optimize initial margin when considering a network of trading participants. Applying CMA-ES, this thesis has explored a new method to handle the nonlinear constraints present in the initial margin optimization problem. LÄS MER

  3. 2. What are the main factors affecting movie profitability?

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Karl Wallström; Markus Wahlgren; [2018]
    Nyckelord :;

    Sammanfattning : This thesis consists of two parts which both focus on the profitability of movies with a theatrical release. The first part has examined if it is possible to create a model for predicting and understanding the profitability of movies. Factors that influence the profitability have also been identified.
