General computer algorithm for constructing the nucleation rate surface is developed. Algorithm is applicable in case of water vapor nucleation. Results can be used in calculations of the water vapor nucleation in atmosphere. An obvious advantage of the computer semi-empirical construction of nucleation rate surfaces is the ability to construct this surface over the whole interval of nucleation parameters that is impossible in experiments. Examples of hard-to-reach conditions include very low temperatures, media with high-pressures and/or very high-temperature (such as stars), etc. It is assumed that the current algorithm can be further developed for semi-empirical construction of nucleation rate surfaces for one- and two-component systems.
