document: Location of transport nets on a heterogeneous territory The location of transport routes on a heterogeneous territory is studied . The network joins a given set of terminal points and a certain number of additional -LRB- branch -RRB- points . The problem is formulated , properties of the optimal solution for a. tree-like network , and the number of branch points are studied . A stepwise optimization algorithm for a. network with given adjacency matrix based on an algorithm for constructing minimal-cost routes is designed
