Nongradient SDEs with small white noise often arise when modeling biological and ecological time-irreversible processes. If the governing SDE were gradient, the maximum …
We present algorithms for solving high-frequency acoustic scattering problems in complex domains. The eikonal and transport partial differential equations from the WKB/geometric …
The classical setting of optimal control theory assumes full knowledge of the process dynamics and the costs associated with every control strategy. The problem becomes much …
We develop a family of compact high-order semi-Lagrangian label-setting methods for solving the eikonal equation. These solvers march the total 1-jet of the eikonal, and use …
We present a family of fast and accurate Dijkstra-like solvers for the eikonal equation and factored eikonal equation which compute solutions on a regular grid by solving local …
Sound propagation in air is accurately described by a small perturbation of the ambient pressure away from a quiescent state. This is the realm of linear acoustics, where the …
We consider three optimal control problems, which focus on continuous path-planning applications, and each problem deals with a specific challenge. First, we introduce a new …

Surveillance-Evasion games are continuous path planning problems in which an evader chooses his trajectory to hinder the surveillance by an enemy observer. In the classical …
Four problems at the intersection of optimization and partial differential equations are presented. First, a problem in remote sensing of the marine atmospheric boundary layer is …
