The main idea of the article is to present to the readers the program for researching the stability of the decision of nonlinear system. The developed program allows to make function of Hamilton, to calculate Jacobian for the basic and interfaced systems, to find points of positions of balance of the decision, to deduce the linear equation of the second order for the interfaced function, and also to calculate expressions of curvature of the decision.

We address the segmentation problem for 3D point clouds retrieved by laser scanning of outdoor scenes. Associative Markov Networks (AMN) are used in the state-of-the-art methods for approaching the problem. An AMN does not allow expressing some natural interactions between objects such as «roof is likely to be above the ground». We use the general form of Markov random fields. It leads to significant performance improvement. We show how to perform inference and tune model's parameters. Oversegmentation is used to subsample a scan in order to improve efficiency and simplify cloud structure.
