TLDR
In the authors' tests, SHOP was several orders of magnitude faster man Blackbox and several times faster than TLpian, even though SHOP is coded in Lisp and the other planners are coded in C.
Abstract
SHOP (Simple Hierarchical Ordered Planner) is a domain-independent HTN planning system with the following characteristics. • SHOP plans for tasks in the same order that they will later be executed. This avoids some goal-interaction issues that arise in other HTN planners, so that the planning algorithm is relatively simple. • Since SHOP knows the complete world-state at each step of the planning process, it can use highly expressive domain representations. For example, it can do planning problems that require complex numeric computations. • In our tests, SHOP was several orders of magnitude faster man Blackbox and several times faster than TLpian, even though SHOP is coded in Lisp and the other planners are coded in C.

Inner Monologue: Embodied Reasoning through Planning with Language Models

TL;DR: In this article , the authors investigate the extent to which large language models can reason over sources of feedback provided through natural language, without any additional training, such as success detection, scene description, and human interaction.

Applications of SHOP and SHOP2

TL;DR: The simple hierarchical ordered planner (SHOP) and its successor, SHOP2, are designed with two goals in mind: to investigate research issues in automated planning and to provide some simple, practical planning tools.

Total-order planning with partially ordered subtasks

TL;DR: The experimental results suggest that in some problem domains, the difficulty of writing SHOP knowledge bases derives from SHOP's total-ordering requirement--and that in such cases, SHOP2 can plan as efficiently as SHOP using knowledge bases simpler than those needed by SHOP.

In defense of PDDL axioms

TL;DR: In this paper, the authors propose an adequate semantics for pddl-like axioms and show that they are an essential feature by proving that it is impossible to compile them away if we restrict the growth of plans and domain descriptions to be polynomial.

Hierarchical planning in BDI agent programming languages: a formal approach

TL;DR: It is argued that the resulting integrated agent programming language combines the advantages of both BDI agent systems and hierarchical offline planners, and cleanly incorporates HTN-style planning as a built-in feature.

A Structure for Plans and Behavior

TL;DR: Progress to date in the ability of a computer system to understand and reason about actions is described, and the structure of a plan of actions is as important for problem solving and execution monitoring as the nature of the actions themselves.

UCPOP: a sound, complete, partial order planner for ADL

TL;DR: It is proved ucpop is both sound and complete for this representation and a practical implementation that succeeds on all of Pednault's and McDermott's examples, including the infamous "Yale Stacking Problem".

Generating project networks

TL;DR: The planner (NONLIN) and the Task Formalism (TF) used to hierarchically specify a domain are described, which can aid in the generation of project networks.

Using temporal logics to express search control knowledge for planning

TL;DR: This work shows how domain dependent search control knowledge can be represented in a temporal logic, and then utilized to effectively control a forward-chaining planner.
