Excerpt from Separating Two Simple Polygons, by a Sequence of Translations
Let P and Q be two disjoint simple polygons having m and n sides respectively. We present an algorithm which determines whether Q can be moved by a sequence of translations to a position sufficiently far from P without colliding with P, and which produces such a motion if it exists. Our algorithm runs in time O(mn a(mn) log m log n) where a(k) is the extremely slowly growing inverse Ackermann's function. Since. In the worst ease O(mn) translations may be necessary to separate Q from P, our algorithm is close to optimal.

Paperback. Zustand: New. Print on Demand. This book presents an innovative algorithm to determine whether two disjoint simple polygons can be moved by a sequence of translations to a position sufficiently far from each other without colliding, and if so, produces such a motion. The algorithm can also determine whether a given polygon can be separated from another using a specified number of translations, and if so, produces a motion using the smallest number of translations or a motion with the shortest total translational distance. The problem that this book addresses is a special instance of the motion planning problem that seeks a purely translational collision-free motion of a polygonal object amidst a collection of polygonal obstacles. The author has shown that the existence of a motion of this type can be determined in time that is close to optimal.
