伪代码演示网络病毒传播机制

在网络病毒传播机制的伪代码演示中，我们可以简化地描述为以下几个步骤：

// 定义病毒节点类 VirusNode
VirusNode:
    id: int
    infected: bool
    neighbors: List[VirusNode]

// 病毒感染函数 infect()
function infect(node: VirusNode, virus_node: VirusNode):
    node.infected = True
    foreach neighbor in node.neighbors:
        if neighbor not infected:
            infect(neighbor, virus_node)

// 网络模型类 NetworkModel
NetworkModel:
    nodes: List[VirusNode]
    connect_nodes(): // 连接节点的方法

// 模拟病毒传播过程
function simulate_virus_spread(model: NetworkModel, initial_infect_node: VirusNode):
    infect(initial_infect_node, model.get_initial_infected_node()) // 根据实际设定找到初始感染者
    while any(node.infected for node in model.nodes): // 当还有未感染节点时
        foreach infected_node in filter(infected, model.nodes): // 遍历所有感染者
            foreach neighbor in infected_node.neighbors:
                infect(neighbor, infected_node)
