This paper proposes a new automatic hypothesis‐generation algorithm for structure–activity relationship (SAR) rules, which is capable of investigating chemical compound activities in the context of multiple substructure interactions. The algorithm is formulated as an optimization problem based on a carefully selected criterion, APostDiff(s), and the globally optimal solution to the optimization problem can be obtained with a fast search algorithm developed using the data‐mining concept known as frequent set . Three public datasets are used to demonstrate the proposed method. Copyright © 2009 Wiley Periodicals, Inc. Analysis and Data Mining 1: 161‐174, 2009
