Аnnotation: The algorithms regularly used in electrical exploration for solving the inverse problem of vertical electrical sounding (VES) can lead to large systematic distortions of the results within the framework of equivalent models. The problem is significantly aggravated when interpreting data from precision geoelectrical monitoring, in particular, during long-term observations by the method of VES. In such cases, it is necessary to use special methods of regularization of the VES inverse problem. The paper proposes improved algorithms for solving the VES inverse problem, which can significantly improve the accuracy and stability of the solution. All these algorithms are implemented in the IPI program and are available for use
