The study considers the problem of constructing routes for the export of timber. The task reduced to building a rooted tree. The study presents two approximate algorithms for solving the problem of covering polygons with rooted trees. To simplify the task, the polygon is covered with a square grid. A greedy algorithm is described that should give an approximate solution. The article also describes the branch and bound method with a reduced number of iteration options. We have reduced the number of iterations by using a special way of building links.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
