- Abstract summary: Large Language Models (LLMs) have been the subject of active research, significantly advancing the field of Natural Language Processing (NLP)
We introduce Plansformer; an LLM fine-tuned on planning problems and capable of generating plans with favorable behavior in terms of correctness and length with reduced knowledge-engineering efforts.
For one configuration of Plansformer, we achieve 97% valid plans, out of which 95% are optimal for Towers of Hanoi - a puzzle-solving domain.

- Abstract: Large Language Models (LLMs) have been the subject of active research,
significantly advancing the field of Natural Language Processing (NLP). From
BERT to BLOOM, LLMs have surpassed state-of-the-art results in various natural
language tasks such as question answering, summarization, and text generation.
Many ongoing efforts focus on understanding LLMs' capabilities, including their
knowledge of the world, syntax, and semantics. However, extending the textual
prowess of LLMs to symbolic reasoning has been slow and predominantly focused
on tackling problems related to the mathematical field. In this paper, we
explore the use of LLMs for automated planning - a branch of AI concerned with
the realization of action sequences (plans) to achieve a goal, typically
executed by intelligent agents, autonomous robots, and unmanned vehicles. We
introduce Plansformer; an LLM fine-tuned on planning problems and capable of
generating plans with favorable behavior in terms of correctness and length
with reduced knowledge-engineering efforts. We also demonstrate the
adaptability of Plansformer in solving different planning domains with varying
complexities, owing to the transfer learning abilities of LLMs. For one
configuration of Plansformer, we achieve ~97% valid plans, out of which ~95%
are optimal for Towers of Hanoi - a puzzle-solving domain.

Large Language Models (LLMs) have shown remarkable performance in various basic natural language tasks.
For completing the complex task, we still need a plan for the task to guide LLMs to generate the specific solutions step by step.
We propose the Learning to Plan method, which involves two phases: (1) In the first learning task plan phase, it iteratively updates the task plan with new step-by-step solutions and behavioral instructions, which are obtained by prompting LLMs to derive from training error feedback.
