3. 22. Using Quality Diversity in Genetic Programming to Improve Automatic Learning of Behaviour Trees

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

   Författare :Alexander Willemsen; [2023]
   Nyckelord :Behaviour Trees; Genetic Programming; Quality Diversity; Gedragsbomen; Genetische Programmering; Kwaliteitsdiversiteit; Beteendeträd; Genetisk Programmering; Kvalitetsmångfald;

   Sammanfattning : One of the main purposes of the fields of Robotics and Artificial Intelligence is to develop solutions that can autonomously solve problems. An important part of this is synthesising behaviours of robots. Behaviour Trees are a tree structure that enables combining existing lower level behaviours into a high level behaviour through task switching. LÄS MER

5. 24. Fracture simulation with a hyperelastic phase field model

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Adrien Fradet; [2023]
   Nyckelord :Fracture; Phase field modeling; Hyperelasticity; Brott; fasfält-methoden; hyperelasticite;

   Sammanfattning : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.
