in this talk we discuss an algorithm to overcome the curse of dimensionality, in possibly non-convex/time/state-dependent hamilton-jacobi partial differential equations. they may arise from optimal control and differential game problems, and are generally difficult to solve numerically in high dimensions. a major contribution of our works is to consider an optimization problem over a single vector of the same dimension as the dimension of the hj pde instead. to do so, we consider hopf-type formulas. the sub-problems are now independent and they can be implemented in an embarrassingly parallel fashion. that is ideal for perfect scaling in parallel computing. the algorithm is proposed to overcome the curse of dimensionality when solving high dimensional hj pde. our method is expected to have application in control theory, differential game problems, and elsewhere. a similar technique can be extended to the computational of a hamilton-jacobi partial differential equations in the wasserstein space, and this is also expected to have applications in mean field control problems and mean field games.
