A new procedure for the analysis of sigmoid autocatalytic curves was developed based on the simulated annealing method. The procedure is particularly well suited to the treatment of asymmetric sigmoid shapes. The method was applied to the autocatalytic oxidation of citric acid with potassium permanganate.
