| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary The proposed meta-heuristic approach aims to develop an effective solution for the k-strong Roman domination problem (SRD) on graph models. This problem generalizes the well-known Roman domination problem and involves assigning integer weights to nodes representing field armies, while satisfying protection constraints and minimizing total weights. The goal is to repel simultaneous attacks on nodes by borrowing armies from neighboring nodes, ensuring self-defense. This problem has practical applications in counter-terrorism strategies, supply chain management, and other areas. A variable neighborhood search algorithm with quasi-feasibility sampling is proposed, showcasing scalability and robustness compared to existing exact approaches. Experiments are conducted using random networks, real-world networks, and GeoJSON files containing geographic features. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary A team of researchers has developed a new way to protect a network from being attacked by many nodes at once. They used a special kind of problem-solving called Roman domination to assign “armies” to each node in the network. The goal is to make sure that any attack can be repelled, or defended against, without losing all the armies on a single node. This problem has important applications in areas like fighting terrorism and managing supply chains. The researchers used a special algorithm to solve this complex problem, which was tested on many different types of networks. |
