Abstract
OBJECTIVE:To investigate the ability of variables selection when an improved GA was used in QSAR study.METHODS:Two data sets:the camptothecin analogs with7,9,10 or 11 substituted and bistriazolols with substituted benzene ring was applied to an improved GA an alysis and PLS was used to fit models.RESULTS:Many better models were obtained than the result obtained by the standard techniques of variables selection in both data sets.CONCLUSION:GA,a heuristic searching algorithms,was suitable for QSAR because it is efficient,rapid and collateral.But it only depends on the statistic fingerposts,so some pretreatment and the checking to GA result is necessary.
