Dai, Pengcheng (author), Yu, Wenwu (author), Wang, He (author), Baldi, S. (author)Actor-critic (AC) cooperative multiagent reinforcement learning (MARL) over directed graphs is studied in this article. The goal of the agents in MARL is to maximize the globally averaged return in a distributed way, i.e., each agent can only exchange information with its neighboring agents. AC methods proposed in the literature require the...journal article 2023

Dai, T. (author), Hein, C.M. (author)A comprehensive understanding of water systems across space and time is key, both for sustainable urban development and heritage preservation. However, so far, a clear methodology that links the exploration of the past and the protection of heritage properties to the design of the future is still missing. We argue that an exploration of heritage...journal article 2023
