The current work considers the problem of arrangement optimization of non-convex polyhedrons into a minimal height parallelepiped container. The no-fit polyhedron based algorithm is proposed to solve described task. The no-fit polyhedrons are used not only for providing conditions of the polyhedrons mutual non-intersection but also for finding the placement points. The current paper provides the block diagrams and the pseudo code of the algorithm. Some examples and computational results are also given for public input data.

The article is devoted to the mathematical modeling of the plant`s development. The graph theory is used to model the plant objects with different types of branching and its growth.
Keywords: model, the plant object, stem, directed graph
