Collective Annealing by Switching Temperatures: a Boltzmann-type description
Frédéric Blondeel, Lorenzo Pareschi, Giovanni Samaey
The design of effective cooling strategies is a crucial component in simulated annealing algorithms based on the Metropolis method. Traditionally, this is achieved through inverse…

Comparison of random field discretizations for high-resolution Bayesian parameter identification in finite element elasticity
Pieter Vanmechelen, Geert Lombaert, Giovanni Samaey
We compare three random field discretization strategies for probabilistic identification of spatially varying material parameters in high-resolution finite element models. These st…

Convergence of the micro-macro Parareal Method for a Linear Scale-Separated Ornstein-Uhlenbeck SDE: extended version
Ignace Bossuyt, Giovanni Samaey, Stefan Vandewalle
Time-parallel methods can reduce the wall clock time required for the accurate numerical solution of differential equations by parallelizing across the time-dimension. In this pape…
