  1. 1. Comparison of two mixed integer solvers with real world data from combinatorial auctions

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Kristoffer Norrman; [2023]
    Nyckelord :;

    Sammanfattning : Coupa is a software company specialising in Business Spending Management, BSM. In the Uppsala office they utilise MIP solvers to help their clients lower sourcing outlays by translating sourcing auc- tions into MIP problems [1] [2]. LÄS MER

  3. 2. Asymmetric Bregman Forward-Backward Splitting with Projection Correction

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Max Nilsson; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis examines first-order Bregman algorithms in a primal and a primal-dual setting. The Bregman gradient descent algorithm is introduced from a majorization-minimization perspective and as a generalization of the gradient descent algorithm. LÄS MER

  4. 3. Data-Driven Methods for Sonar Imaging

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Lovisa Nilsson; [2021]
    Nyckelord :Sonar; Reconstruction; Inverse Problems; Deep Learning; Data-driven Methods;

    Sammanfattning : Reconstruction of sonar images is an inverse problem, which is normally solved with model-based methods. These methods may introduce undesired artifacts called angular and range leakage into the reconstruction. LÄS MER

  5. 4. Model selection and optimization experiment of a field trial with agricultural data using Python

    Kandidat-uppsats, Lunds universitet/Matematik LTH

    Författare :Lukas Bengtsson; [2018]
    Nyckelord :ADMM; Elastic Net; Model selection; optimization; Mathematics and Statistics;

    Sammanfattning : Potato cultivation is vast for many agricultures in southern Sweden. What many might not be aware of, is how much pesticides which are used in the cultivation process. In "Late blight prediction and analysis"[1] predictions of late-blight attacks was modelled on potato-corps using Elastic Net among other methods. LÄS MER

  7. 5. Preconditioned iterative methods for PDE-constrained optimization problems with pointwise state constraints

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Anders Ström; [2017]
    Nyckelord :;

    Sammanfattning : Optimization problems constrained by partial differential equations (PDEs) arise in a variety of fields when one wants to optimize a system governed by a PDE. The goal is to compute a control variable such that a state variable is as close as possible to some desired state when control and state are coupled by some PDE. LÄS MER
