Next, let us compare our predicted octanol/water partition coefficients to the provided experimental data. For the competition, we made submissions using neat 1octanol and water-saturated 1-octanol using TIP4P water. At the close of the challenge the challenge organizers analyzed the results and reported for our predictions using neat 1-octanol a RMSE of 1.08 which ranked 1/10 in the "Physical (MM)" category, while our predictions using water-saturated 1-octanol had a RMSE of 1.47 and ranked 6/10 in the Physical (MM) category. Computing independently here we find an average absolute error (AAE) and RMSE of 0.83 and 1.11 for neat 1-octanol, and an AAE and RMSE of 1.30 and 1.47 for water-saturated 1-octanol. Considering the average uncertainty in our predicted octanol/water partition coefficients is 0.08 and 0.10 using neat 1-octanol and water-saturated 1-octanol, respectively, the difference in AAE and RMSE of 0.48 and 0.37 is significant. Interestingly, while the use of water-saturated 1-octanol is a better representation of the physical system, we find that the predictions using neat 1-octanol are in better quantitative agreement with the experimental data. This is a fortuitous result.
