Generalized Planning for the Abstraction and Reasoning Corpus

1 code implementation15 Jan 2024 Chao Lei, Nir Lipovetzky, Krista A. Ehinger

The Abstraction and Reasoning Corpus (ARC) is a general artificial intelligence benchmark that poses difficulties for pure machine learning methods due to its requirement for fluid intelligence with a focus on reasoning and abstraction.

Diverse, Top-k, and Top-Quality Planning Over Simulators

no code implementations25 Aug 2023 Lyndon Benke, Tim Miller, Michael Papasimeon, Nir Lipovetzky

Diverse, top-k, and top-quality planning are concerned with the generation of sets of solutions to sequential decision problems.

Lifted Sequential Planning with Lazy Constraint Generation Solvers

no code implementations17 Jul 2023 Anubhav Singh, Miquel Ramirez, Nir Lipovetzky, Peter J. Stuckey

This paper studies the possibilities made open by the use of Lazy Clause Generation (LCG) based approaches to Constraint Programming (CP) for tackling sequential classical planning.

Novelty and Lifted Helpful Actions in Generalized Planning

no code implementations3 Jul 2023 Chao Lei, Nir Lipovetzky, Krista A. Ehinger

It has been shown recently that successful techniques in classical planning, such as goal-oriented heuristics and landmarks, can improve the ability to compute planning programs for generalized planning (GP) problems.

Sampling from Pre-Images to Learn Heuristic Functions for Classical Planning

no code implementations7 Jul 2022 Stefan O'Toole, Miquel Ramirez, Nir Lipovetzky, Adrian R. Pearce

We introduce a new algorithm, Regression based Supervised Learning (RSL), for learning per instance Neural Network (NN) defined heuristic functions for classical planning problems.

Width-based Lookaheads with Learnt Base Policies and Heuristics Over the Atari-2600 Benchmark

no code implementations NeurIPS 2021 Stefan O'Toole, Nir Lipovetzky, Miquel Ramirez, Adrian Pearce

We propose new width-based planning and learning algorithms inspired from a careful analysis of the design decisions made by previous width-based planners.

Planning for Novelty: Width-Based Algorithms for Common Problems in Control, Planning and Reinforcement Learning

no code implementations9 Jun 2021 Nir Lipovetzky

Width-based algorithms search for solutions through a general definition of state novelty.

Approximate Novelty Search

no code implementations17 May 2021 Anubhav Singh, Nir Lipovetzky, Miquel Ramirez, Javier Segovia-Aguas

Width-based search algorithms seek plans by prioritizing states according to a suitably defined measure of novelty, that maps states into a set of novelty categories.

Planimation

1 code implementation11 Aug 2020 Gang Chen, Yi Ding, Hugo Edwards, Chong Hin Chau, Sai Hou, Grace Johnson, Mohammed Sharukh Syed, Haoyuan Tang, Yue Wu, Ye Yan, Gil Tidhar, Nir Lipovetzky

Planimation is a modular and extensible open source framework to visualise sequential solutions of planning problems specified in PDDL.

Novelty Messages Filtering for Multi Agent Privacy-preserving Planning

no code implementations18 Jun 2019 Alfonso E. Gerevini, Nir Lipovetzky, Nico Peli, Francesco Percassi, Alessandro Saetti, Ivan Serina

In multi-agent planning, agents jointly compute a plan that achieves mutual goals, keeping certain information private to the individual agents.

Best-First Width Search for Multi Agent Privacy-preserving Planning

no code implementations10 Jun 2019 Alfonso E. Gerevini, Nir Lipovetzky, Francesco Percassi, Alessandro Saetti, Ivan Serina

In multi-agent planning, preserving the agents' privacy has become an increasingly popular research topic.

What you get is what you see: Decomposing Epistemic Planning using Functional STRIPS

no code implementations28 Mar 2019 Guang Hu, Tim Miller, Nir Lipovetzky

Epistemic planning --- planning with knowledge and belief --- is essential in many multi-agent and human-agent interaction domains.
