摘要:

在本文中,我们提出了一种新的算法的布局优化问题:这涉及到放置加权多边形内的圆形容器,两个目标是最大限度地减少不平衡的质量和最小化的半径的容器。这个问题在工业应用(如卫星设计)中具有实际意义,同时也具有重要的理论意义。以前的工作已经处理了圆形或矩形对象,但在这里,我们处理更现实的情况下,对象可以表示为多边形和多边形允许旋转。我们提出了一种基于模拟退火的解决方案,并首先在已知最优解的实例上进行测试。我们的研究结果表明,该算法获得的容器半径接近最优。我们还比较我们的方法与现有的算法(特殊)矩形的情况下。实验结果表明,我们的方法在解质量方面优于这些方法。

英文摘要:

In this paper we present a new algorithm for a layout optimization problem: this concerns the placement of weighted polygons inside a circular container, the two objectives being to minimize imbalance of mass and to minimize the radius of the container. This problem carries real practical significance in industrial applications (such as the design of satellites), as well as being of significant theoretical interest. Previous work has dealt with circular or rectangular objects, but here we deal with the more realistic case where objects may be represented as polygons and the polygons are allowed to rotate. We present a solution based on simulated annealing and first test it on instances with known optima. Our results show that the algorithm obtains container radii that are close to optimal. We also compare our method with existing algorithms for the (special) rectangular case. Experimental results show that our approach out-performs these methods in terms of solution quality.
