Отрывок: One iteration of Hebene algorithm. Figure 3. Hebene algorithm. Thus, the algorithm depicted in the flowcharts is divided into two procedures. The first procedure exchanges all pairs of vertices, and if the value of the goal function is improved, then it returns true, otherwise false. The second procedure executes the first procedure until it returns false. 4. Some results of computational experiments First of all, let us give an illustrative example of the work of Hebene algorithm for placing...

Аннотация : The paper is devoted to the problem of placing a graph. Graphs provide an opportunity to present information in a visual and easy to understand form, so the problem of developing various algorithms for automatic placement of graphs on the plane is very relevant. In this paper, we propose a generalized mathematical model of the problem that allows us to consider the placement problem in n-dimensional space as the problem of finding a permutation of n elements. Based on the mathematical description “Hebene”, an heuristic algorithm is built. Computational experiments were carried out on all pairwise nonisomorphic connected graphs up to and including 9. The algorithm found the optimal solution in more than 50% of cases, and in other situations the algorithm also produced acceptable solutions.
