+**Title:** ACPBench: Reasoning About Action, Change, and Planning
+**Pdf:** https://arxiv.org/pdf/2410.05669
+**Task:** `acp_bench`
+**Abstract:**
 
 There is an increasing body of work using Large Language Models (LLMs) as agents for orchestrating workflows and making decisions in domains that require planning and multi-step reasoning. As a result, it is imperative to evaluate LMs on core skills required for planning. ACPBench is a benchmark for evaluating the reasoning tasks in the field of planning. The benchmark consists of 7 reasoning tasks over 13 planning domains. The collection is constructed from planning domains described in a formal language. This allows the synthesized problems to have provably correct solutions across many tasks and domains. Further, it allows the luxury to scale without additional human effort, i.e., many additional problems can be created automatically.

+**Title:** ACPBench Hard: Unrestrained Reasoning about Action, Change, and Planning
+**Pdf:** https://arxiv.org/abs/2503.24378
+**Task:** `acp_bench_hard`
+**Abstract:**
+
+We introduce ACPBench Hard, a dataset of generative, open-ended questions which LLM models needs to answer in order to plan. Models that perform well on these tasks could in principle be integrated into a planner or be used directly as a policy. We discuss the complexity of these tasks as well as the complexity of validating the correctness of their answers and present validation algorithms for each task. Equipped with these validators, we test the performance of a variety of models on our tasks and find that for most of these tasks, the performance of even the largest models is still subpar. Our experiments show that no model outperforms any other in these tasks, and with a few exceptions, all tested language models score below 65\%, indicating that even the current frontier language models as well as so-called reasoning models have a long way to go before they can reliably reason about planning.

+  - context: "There are several cities, each containing several locations, some of which are airports. There are also trucks, which can drive within a single city, and airplanes, which can fly between airports. The goal is to get some packages from various locations to various new locations. \nThere are 2 trucks and 1 airplane, as well as 4 packages. There are 4 locations across 2 cities. \nThe locations are in cities as follows: l0-1 and l0-0 are in c0; l1-0 and l1-1 are in c1. \nCurrently, a0 and t0 are at l0-0, t1 is at l1-1, p2, p1, and p3 are at l1-0, p0 is in t1. The goal is to reach a state where the following facts hold: p1 is at l1-0, p0 is at l0-0, p2 is at l1-0, and p3 is at l0-1. The available propositions are: (at ?obj ?loc) - ?obj is at ?loc and (in ?obj1 ?obj2) - ?obj1 is in ?obj2."
