  1. 1. Using Data-Driven Feasible Region Approximations to Handle Nonlinear Constraints When Applying CMA-ES to the Initial Margin Optimization Problem

    University essay from KTH/Matematisk statistik

    Author : Karl Wallström; [2021]
    Keywords : Optimization; Initial margin; Evolutionary algorithms; CMA-ES; Support vector machines; Boundary constraint handling; Nonlinear constraints; Repair algorithms; Feasible region approximation; Optimering; Initial margin; Evolutionära algoritmer; CMA-ES; Support vector machines; Hantering av bivillkor; Icke-linjära bivillkor; Reparationsalgoritmer; Approximation av tillåtet område;

    Abstract : 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. READ MORE

  2. 2. Deep Learning for Dynamic Portfolio Optimization

    University essay from KTH/Matematisk statistik

    Author : Victor Molnö; [2021]
    Keywords : Dynamic portfolio optimization; No-trade-region; Deep learning; Policy iteration; Dynamisk portföljoptimering; Handelsstoppregion; Djupinlärning; Policyiterering;

    Abstract : This thesis considers a deep learning approach to a dynamic portfolio optimization problem. A proposed deep learning algorithm is tested on a simplified version of the problem with promising results, which suggest continued testing of the algorithm, on a larger scale for the original problem.

  3. 3. A Space-Time Study of the Electron-Electron Interaction in High-TC Parent Compound La2CuO4: In Search of an Attractive Effective Interaction

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Tor Sjöstrand; [2016]
    Keywords : Physics and Astronomy;

    Abstract : The superconductivity under doping in the famous cuprate compounds is believed to originate in the CuO2 planes. The mediator of pairing is generally accepted to be induced from electronic degrees of freedom. READ MORE

  4. 4. HYDRODYNAMIC OPTIMIZATION OF TWO-DIMENSIONAL MULTI-ELEMENT TRAWL-DOOR SHAPES USING LOCAL SURROGATE MODELS AND ANALYSIS OF CONTROLLABLE TRAWL-DOOR SHAPES

    University essay from KTH/Kraft- och värmeteknologi

    Author : Magnus Juliusson; [2013]
    Keywords : ;

    Abstract : The study is motivated by the quest to lower the fuel consumption of trawlers and reduce green house gas emissions. Conventional trawl-doors contribute to about one third of the trawlers fuel consumption. Design and optimization of trawl-doors using computational models is vital in minimizing the fuel consumption.
