Abstract(in English) | A linkage is a collection of line segments, called bars, possibly joined at their ends, called joints. A planar reconfiguration of a linkage is a continuous motion of their bars, preserving the length of each bar and disallowing bars to cross. In this paper, we introduce a class of linkages, called "monotone trees, " and give a method for reconfiguring a monotone tree to a straight line. If the tree has n joints, then the method takes at most n-1 moves, each of which uses two joints. We also obtain an algorithm to find such a method in time Ο(n log n), using space Ο(n). These time and space complexities and optimal. |
