An Effective Hybrid Algorithm for the Circles and Spheres Packing Problemsan be packed without overlap. Circular containers are considered. Moreover, 2D and 3D problems are treated. Lacking powerful optimization method is the key obstacle to solve this kind of problems. The energy landscape paving (ELP) method is a class of heuristic global optimization algorithm. By comb

On-Line Multiple-Strip Packingum height among strips used is minimized. A number of on-line algorithms for this problem are proposed, in which the decision of delivering the rectangles to strips as well as packing the rectangles in strips must be done on-line. Both randomized and deterministic on-line algorithms are investigated

Improved Bounds for Facility Location Games with Fair Cost Allocationaph and pays connection cost to the chosen node, and shares fairly facility installation cost with other agents having chosen the same location. This game has pure strategy Nash equilibria, that can be found by simple improvements performed by the agents iteratively. We show that this algorithm may

Two-Level Heaps: A New Priority Queue Structure with Applications to the Single Source Shortest Pathretical Computer Science on account of its wide applicability to practical situations. This problem was first solved in polynomial time by Dijkstra , who showed that by extracting vertices with the smallest distance from the source and relaxing its outgoing edges, the shortest path to each

On Construction of Almost-Ramanujan Graphs the second largest eigenvalue .(..). In the same paper, they ask whether or not the similar technique can be used to construct expanders with the second largest eigenvalue .(..). Such graphs are called Ramanujan graphs. Recently, zig-zag product has been generalized by Ben-Aroya and Ta-Shma. Using

Conference proceedings 2009in Huangshan, China, in June 2009. The 50 revised full papers were carefully reviewed and selected from 103 submissions. The papers feature original research in the areas of combinatorial optimization - both theoretical issues and and applications motivated by real-world problems thus showing convin
