    • A method for operating a machine for identifying a mechanism associated with a cellular response includes identifying molecules participating in the cellular response, accessing a database containing information characterizing molecular interactions, determining pathways connecting the identified molecules participating in the response, and solving an optimization problem. The pathways comprise nodes, each representing a molecule, and edges, each connecting a pair of nodes and representing an interaction between a respective pair of molecules represented by the pair of nodes. The nodes includes a subset that represent molecules identified as participating in the cellular response. Solving an optimization problem comprises determining a subset of the molecules and interactions having a minimum aggregate cost, associating each participating node with a penalty value, associating each edge with a cost value, forming an objective function based on the penalty and cost values, and identifying the sub-network of nodes and edges that minimizes the objective function.
    • 用于操作用于识别与细胞反应相关的机制的机器的方法包括识别参与细胞反应的分子,访问包含表征分子相互作用的信息的数据库,确定参与响应的所识别分子的连接途径以及解决优化问题。 这些路径包括每个表示分子的节点和边缘,每个节点连接一对节点并且表示由该对节点表示的相应的一对分子之间的相互作用。 节点包括表示被鉴定为参与细胞反应的分子的子集。 解决优化问题包括确定分子的子集和具有最小总成本的交互,将每个参与节点与惩罚值相关联,将每个边缘与成本值相关联,基于惩罚和成本值形成目标函数,以及识别 节点和边缘的子网络使目标函数最小化。
