In this paper, we present a new biological model for this purpose and discuss the solution of the large-scale nonlinear optimization problems originating from it. The model includes equivalent uniform dose and partial volume constraints and employs the tumor control probability as the objective. The resulting optimization problems are convex and nonconvex constrained optimization problems with several thousands of variables, for which gradients of the involved functions are available, but the computation of Hessians is numerically too costly. It is suggested to solve these problems with a barrier-penalty multiplier method by Polyak, Ben-Tal and Zibulevsky, where this algorithm is modified according to ideas which are motivated by a related Lagrangian barrier algorithm of Conn, Gould, and Toint. In particular, the subproblems in the algorithm are solved by a conjugate gradient method, since the spectrum of the Hessian of the Lagrangian at a solution of such problem indicates fast (local) convergence of the objective function values to a good approximate (locally) optimal value. Some characteristic numbers showing the average numerical performance of the algorithm are tabulated for various types of tumors and a set of 127 clinical cases in total. Its capabilities and typical behavior also are illustrated explicitly by a computed therapy plan for a difficult clinical case of a larynx tumor.

We present the construction of optimal transit routes in Afghanistan through mathematical optimization. Basically there are three different optimization goals (a) the shortest route w.r.t. the distance, (b) the cheapest route w.r.t. the construction cost, and (c) the most convenient route w.r.t. the elevation change. It is possible to combine two objectives by considering the Pareto front. For the design and modeling of the routes, a computer program named “Contra ” (Computing an Optimal Network of Transit Routes through mathematical Algorithms) was developed. As a demonstrator example, we compute Pareto-optimal routes between two Afghan cities.

Here the nodes (objects, targets) are not static, they are moving over time on trajectories. Moreover, each target has a visibility time window and it can be reached by a salesman only within that time window. The objective function is to minimize the total traveled distances of all salesmen. We recall the time-discrete model formulation from Stieber et al. [9]. This model is applicable to arbitrarily shaped trajectories. Thus, we generated non-linear trajectories based on polynomials, trigonometric functions and their combinations. Computational experiments are carried out with up to 16 trajectories and the results are compared to the ones obtained with linear trajectories.

From the differences in the arrival times of these sounds, it is possible to determine the location of surrounding objects. The propagation of underwater sound is a complex issue that involves several factors, such as the density and pressure of the water, the salinity and temperature level, as well as the pulse length and volume and the reflection properties of the surface. These effects can be approximated by nonlinear equations. Furthermore, natural obstacles in the water, such as the coastline, need to be taken into consideration. Given a certain area of the ocean that should be endowed with a sonar system for surveillance, we consider the task of determining how many sources and receivers need to be deployed, and where they should be located. We give an integer nonlinear formulation for this problem, and several ways to derive an integer linear formulation from it. These formulations are numerically compared using a test bed from coastlines around the world and a state-of-the-art MIP solver (CPLEX).

The question arises how to construct such a structure in a convenient way so that it is structurally as stable as possible. In this paper, we consider the automatic construction of a honeycomb structure, given the boundary of a shape of interest. In doing this we employ Lloyd’s algorithm in two different realisations. For computing the incorporated Voronoi tessellation we consider the use of a Delaunay triangulation or the Eikonal equation. As a main point of our paper, we give a comparison of these two methods. We show that one can make use of the arising graph of the honeycomb structure as input for a specific routing scheme that enhances printability when the printing material stays soft for some time during the printing process.
