First paragraph (this article has no abstract)

Topological (2D) Fuzzy Pharmacophore Triplets (2D-FPT), using the number of interposed bonds to measure separation between the atoms representing pharmacophore types, were employed to establish and validate Quantitative Structure-Activity Relationships (QSAR). Thirteen data sets for which state-of-the-art QSAR models were reported in literature were revisited in order to benchmark 2D-FPT biological activity-explanatory propensities. Linear and non-linear QSAR models were constructed for each compound series (following the original author's splitting into training/validation subsets) with three different 2D-FPT versions, using the Genetic Algorithm (GA)-based Stochastic QSAR Sampler (SQS) to pick relevant triplets and fit their coefficients.
