Reproducibility Variable Result LLM Response
Research Type Theoretical In this paper, we give answers to all three open problems. First, we show a tight upper bound of cost ratio for graphs, and confirm the conjecture by Kleinberg and Oren that Akerlof s structure is indeed the worst case for cost ratio. Second, we prove that finding a motivating subgraph is NP-hard, showing that it is generally inefficient to motivate agents by deleting nodes and edges in the graph. Last but not least, we show that computing a strategy to place minimum amount of total reward is also NP-hard and we provide a 2napproximation algorithm.
