  1. 1. Models of superconductors with correlated defects

    Master-uppsats, KTH/Fysik

    Författare :Jakob Bolin; [2022]
    Nyckelord :Quantum phase transition; correlated disorder; 3D XY model; Monte Carlo simulation; worm algorithm; winding number; superfluid density; Kvantfasövergång; korrelerad oordning; 3D XY modell; Monte Carlo simulering; worm algoritmen; vindlingstal; supraledande täthet;

    Sammanfattning : The quantum phase transition between groundstates of a system with correlated disorder near absolute zero is studied. The computations are based on Monte Carlo methods and the worm algorithm which is an effective method to simulate basic models like the Ising and XY model by making use of global Monte Carlo moves given by modified random walks.

  3. 2. Monte-Carlo Tree Search Used for Fortification in the Game of Risk

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jakob Bolin; Nico Palmroos; [2020]
    Nyckelord :Risk board game; Monte Carlo tree search; Progressive bias; Hierarchical search;

    Sammanfattning : The strategy game Risk is a very popular boardgame, requiring little effort to learn but lots of skill to master.The aim of this project is to explore the fortification phase of thegame, where the player’s troops are moved between territories.Our method is based on adapting Monte Carlo tree search(MCTS) to Risk.
