Abstract
Application of four algorithms developed for detecting optical vortices in problems of singular optics is considered. Structure of numerical models and design of corresponding computational application are described; input parameters required for the model implementation are listed. Special attention is devoted to precision of vortex coordinates and number. Depending on these characteristic, suggestions are made for possible application of the algorithms: two of them can only be used in theoretical studies, while other two can be applied in real laboratory experiments.
