Researchers have introduced risk-aware general-utility Markov decision processes (GUMDPs) to allow agents to optimize risk measures of objective values, enabling a trade-off between expected performance and risk aversion. The proposed framework focuses on the entropic risk measure (ERM) and demonstrates how these risk-aware GUMDPs can be solved using online planning techniques, specifically Monte Carlo Tree Search (MCTS). Experimental results show the approach's effectiveness across various tasks, including standard MDPs, exploration, imitation learning, and multi-objective MDPs. AI
