Playout Policy Adaptation for Games
Abstract. Monte Carlo Tree Search (MCTS) is the state of the art algorithm for General Game Playing (GGP). We propose to learn a playout policy online so as to improve MCTS for GGP...

Comparing the performance of natural, semi-natural, and non-natural locomotion techniques in virtual reality
One of the goals of much virtual reality (VR) research is to increase realism. In particular, many techniques for locomotion in VR attempt to approximate real-world walking. Howev...

A spatial partitioning heuristic for automatic adjustment of the 3D navigation speed in multiscale virtual environments
With technological evolution, 3D virtual environments continuously increase in complexity; such is the case with multiscale environments, i.e., environments that contain groups of...

Exact Algorithms for L1-TV Regularization of Real-Valued or Circle-Valued Signals
We consider L1-TV regularization of univariate signals with values on the real line or on the unit circle. While the real data space leads to a convex optimization problem, the pr...

An Efficient Filtered Scheme for Some First Order Time-Dependent Hamilton-Jacobi Equations
We introduce a new class of “filtered” schemes for some first order non-linear Hamilton-Jacobi equations. The work follows recent ideas of Froese and Oberman (SIAM J. Numer. ...
