Planning with a Learned Policy Basis to Optimally Solve Complex Tasks
Conventional reinforcement learning (RL) methods can successfully solve a wide range of sequential decision problems.
Asymmetric Norms to Approximate the Minimum Action Distance
Our results show that our asymmetric norm parametrization performs comparably to symmetric norms in symmetric environments and surpasses symmetric norms in asymmetric environments.
Generalized Planning as Heuristic Search: A new planning search-space that leverages pointers over objects
First, the paper introduces a new pointer-based solution space for GP that is independent of the number of classical planning instances in a GP problem and the size of those instances (i. e. the number of objects, state variables and their domain sizes).
Hierarchies of Reward Machines
Reward machines (RMs) are a recent formalism for representing the reward function of a reinforcement learning task through a finite-state machine whose edges encode subgoals of the task using high-level events.

This paper adapts the planning as heuristic search paradigm to the particularities of GP, and presents the first native heuristic search approach to GP.
Scaling-up Generalized Planning as Heuristic Search with Landmarks
In this paper we define a landmark counting heuristic for GP (that considers sub-goal information that is not explicitly represented in the planning instances), and a novel heuristic search algorithm for GP (that we call PGP) and that progressively processes subsets of the planning instances of a GP problem.
