1 Introduction Pyramid schemes' are large scale scam operations that fool ordinary people with little to no experience in investment or marketing. Such organizations promise new members that if they can convince other people to join, they will receive commissions or other bonuses. This idea benefits people who joined early (usually the directors of the organization) but leaves most members with great losses, simply because no new member will join after some time.

While Doe was arrested on drug charges, police found evidence of a running pyramid network on his computer. He kept detailed logs of who joined the network, how and when, as well as how much assets they currently have Toronto police is now planning for Operation Sahure to crack down on this pyramid scheme. However due to recent budget cuts, there is only one unit to be sent to make arrests. So, they can only arrest one person at a time. After arresting a person, all of their illegal assets will be seized. Considering that the news of arrest will be public in a few hours after the first arrest, the police only have time to arrest at most a specific number of suspects. They want to maximize the amount of assets that they seize from suspects. Furthermore, they do not have the location of members. The Crown Attorney prepared a deal for any arrested member to receive reduced charges when they reveal the location of another member to police However, each member only knows a few other members in the network, a policy that was strictly enforced to protect the network from mass arrests. Every arrested member will accept the deal, if offered. Doe also accepted a deal from the Crown Attorney to disclose the location of one member to the police in exchange for a reduced sentence. Now the police want to decide which group member they should select to arrest, to maximise the seized assets considering all limitations.
