A Framework for OpenGL Client-Server Rendering
Dyken, Erik Christopher; Lye, Kjetil Olsen; Seland, Johan Simon; Bjønnes, Erik W; Hjelmervik, Jon M.; Nygaard, Jens Olav; Hagen, Trond Runar (Chapter, 2012)We present a software framework that facilitates the development of OpenGL applications utilizing the limited GPU capacities of a portable client in combination with the high-end rendering hardware on a server. The resulting ... -
Constraint Preserving Mixers for the Quantum Approximate Optimization Algorithm
Fuchs, Franz Georg; Lye, Kjetil Olsen; Nilsen, Halvor Møll; Stasik, Alexander Johannes; Sartor, Giorgio (Peer reviewed; Journal article, 2022)The quantum approximate optimization algorithm/quantum alternating operator ansatz (QAOA) is a heuristic to find approximate solutions of combinatorial optimization problems. Most of the literature is limited to quadratic ... -
Convergence Rates of Monotone Schemes for Conservation Laws for Data with Unbounded Total Variation
Fjordholm, Ulrik Skre; Lye, Kjetil Olsen (Peer reviewed; Journal article, 2022)We prove convergence rates of monotone schemes for conservation laws for Hölder continuous initial data with unbounded total variation, provided that the Hölder exponent of the initial data is greater than 12/. For strictly ... -
Iterative Surrogate Model Optimization (ISMO): An active learning algorithm for PDE constrained optimization with deep neural networks
Lye, Kjetil Olsen; Mishra, Siddhartha; Ray, Deep; Chandrasekhar, Praveen (Peer reviewed; Journal article, 2020)We present a novel active learning algorithm, termed as iterative surrogate model optimization (ISMO), for robust and efficient numerical approximation of PDE constrained optimization problems. This algorithm is based on ...
