你好，想请教一下该模型动态多跳推理流模块的细节

你好，想请问一下在论文3.2.3部分提到的计算未访问节点分数相关细节。1、在生成输出序列的每个时间步，是否计算节点分数都会从初始节点为1其他节点为0开始，还是会在上个时间步的分数基础上更新呢？2、论文4.2部分说到“Specifically, we iterate the following process for H hops: starting from the nodes in the current sub-graph (initialized by Cx) and search for the direct neighbours of each node and preserve topB nodes with the connected edges to enlarge the sub-graph”，表明每一跳会访问top-B个节点，而3.2.2部分提到“Specifically, the module broadcasts information on G by updating the score of outer nodes with their visited neighbours for multiple hops until all the nodes on G are visited.”，表示图G上的所有节点都会被访问，如果每一跳访问top-B个节点，到H跳后不会有节点未被访问吗？
