# satbench / 93 - taskset: [satbench](https://harnessreport.com/tasks/satbench.md) - difficulty: medium - category: reasoning - language: - runnable from the site: no - agent timeout: 600s ## Results by harness _none yet_ ## Instruction ``` Solve this logical puzzle problem and write your answer to solution.txt without asking for my approval. You are a logical reasoning assistant. You are given a logic puzzle. <scenario> Four scientists—Dr. Smith, Dr. Johnson, Dr. Patel, and Dr. Zhang—are each considering whether to participate in a groundbreaking research project. Each scientist makes an independent decision about their participation, without any influence or constraint from the others. <conditions> 1. Either Dr. Smith does not join the research project, or Dr. Patel joins. 2. Either Dr. Smith does not join the project, or Dr. Patel does not join. 3. Either Dr. Smith or Dr. Patel joins the research project. 4. Either Dr. Smith joins the research project, or Dr. Patel does not join. 5. Either Dr. Smith joins the research project, or Dr. Johnson does not join, or Dr. Zhang does not join. <question> Can all these participation decisions be made simultaneously? Guidelines: - All constraints come **only** from the <conditions> section. - The <scenario> provides background and intuition, but **does not impose any additional rules or constraints**. - All variables represent **independent decisions**; there is no mutual exclusivity or implicit linkage unless stated explicitly in <conditions>. - Variables not mentioned in <conditions> are considered unknown and irrelevant to satisfiability. Your task: - If the puzzle is satisfiable, propose one valid assignment that satisfies all the conditions. - If the puzzle is unsatisfiable, explain why some of the conditions cannot all be true at once. Think step by step. At the end of your answer, output exactly one of the following labels on a new line of the solution.txt file: [SAT] — if a valid assignment exists [UNSAT] — if the constraints cannot be satisfied Do not add any text or formatting after the final label. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
