Researchers have developed a new approach to address long-horizon decision problems where immediate rewards can lead to detrimental long-term consequences. Their work identifies two key failure modes in policy-gradient methods: 'completion' (reaching the end of the horizon) and 'optimality' (achieving the best possible outcome). By separating these modes, they propose a method that improves completion rates and reduces the optimality gap, demonstrating its effectiveness in simulated environments like a bricklayer career and an NBA player career.
