arXiv 2019年
作者: Carmona, René Laurière, Mathieu Program in Applied and Computational Mathematics and Orfe
We propose two algorithms for the solution of the optimal control of ergodic McKean-Vlasov dynamics. Both algorithms are based on approximations of the theoretical solutions by neural networks, the latter being charac... 详细信息
