Between the folds a film about finding inspiration in unexpected places ( Visual )
2 editions published in 2009 in English and held by 877 WorldCat member libraries worldwide
Origami may seem an unlikely medium for understanding and explaining the world. But around the globe, several fine artists and theoretical scientists are abandoning more conventional career paths to forge lives as modern-day paper folders. Through origami, these offbeat and provocative minds are reshaping ideas of creativity and revealing the relationship between art and science. This film chronicles 10 of their stories: three of the world's foremost origami artists, less conventional artists, abstract artists, advanced mathematicians and a remarkable scientist who received a MacArthur Genius Award for his computational origami research. While debates ebb and flow on issues of folding technique, symbolism and purpose, this film shows how closely art and science are intertwined. The medium of paper folding--a simple blank, uncut square--emerges as a metaphor for the creative potential of transformation in all of us
Geometric folding algorithms : linkages, origami, polyhedra by Erik D Demaine ( Book )
20 editions published between 2007 and 2010 in English and held by 417 WorldCat member libraries worldwide
Folding and unfolding problems have been implicit since Albrecht Dürer in the early 1500s, but have only recently been studied in the mathematical literature. Emphasising algorithmic or computational aspects, this treatment of the geometry of folding and unfolding presents over 60 unsolved 'open problems' to spur further research
A lifetime of puzzles : a collection of puzzles in honor of Martin Gardner's 90th birthday ( Book )
5 editions published in 2008 in English and held by 261 WorldCat member libraries worldwide
"This collection is a tribute to Martin Gardner by mathematicians, puzzle masters, and magicians. It was conceived and initiated in honor of his 90th birthday and is finally published as he celebrates his 94th year, maintaining the inspiring creativity that has motivated so many professional mathematicians and amateurs, who are all dedicated to his unique amalgamation of rational thought and magic. Some of the contributions celebrate the life of Martin Gardner; some tell about his influence on individuals or on the field of recreational mathematics in general; some are puzzles or tricks inspired by Martin Gardner and his work." "Martin Gardner stands at the intersection of magic and mathematics. Mathematical magic, like chess, has its own curious charms, he says. [It] combines the beauty of mathematical structure with the entertainment value of a trick. Martin Gardner has been writing about magic and contributing new effects for nearly seventy years. Today, he keeps in contact with magicians like Penn and Teller by phone and receives occasional visits from magicians who come to trade notes with him. In 1999 he was named one of MAGIC Magazine s 100 most influential magicians of the twentieth century."--Jacket
Games, puzzles, and computation by Robert A Hearn ( Book )
7 editions published in 2009 in English and held by 225 WorldCat member libraries worldwide
The authors show that there are underlying mathematical reasons for why games and puzzles are challenging (and perhaps why they are so much fun). They also show that games and puzzles can serve as powerful models of computation-quite different from the usual models of automata and circuits-offering a new way of thinking about computation. The appendices provide a substantial survey of all known results in the field of game complexity, serving as a reference guide for readers interested in the computational complexity of particular games, or interested in open problems about such complexities

Approximation algorithms via contraction decomposition by Erik D Demaine ( Book )
4 editions published between 2006 and 2010 in English and held by 5 WorldCat member libraries worldwide
We prove that the edges of every graph of bounded (Euler) genus can be partitioned into any prescribed number $k$ of pieces such that contracting any piece results in a graph of bounded treewidth (where the bound dependson~$k$). This decomposition result parallels an analogous, simpler result for edge deletions instead of contractions, obtained by Baker, Eppstein, and others, and it generalizes a similar result for "compression" (a variant of contraction) in planar graphs (Klein). Our decomposition result is a powerful tool for obtaining PTASs for contraction-closed problems (whose optimal solution only improves under contraction), a much more general class than minor-closed problems. We prove that any contraction-closed problem satisfying just a few simple conditions has a PTAS in bounded-genus graphs. In particular, our framework yields PTASs for the weighted Traveling Salesman Problem and for minimum-weight $c$-edge-connected submultigraph on bounded-genus graphs, improving and generalizing many previous algorithms. We also highlight the only main difficulty in extending our results to general $H$-minor-free graphs
Folding and unfolding by Erik D Demaine ( )
2 editions published between 2001 and 2004 in English and held by 4 WorldCat member libraries worldwide
The results of this thesis concern folding of one-dimensional objects in two dimensions: planar linkages. More precisely, a planar linkage consists of a collection of rigid bars (line segments) connected at their endpoints. Foldings of such a linkage must preserve the connections at endpoints, preserve the bar lengths, and (in our context)prevent bars from crossing. The main result of this thesis is that aplanar linkage forming a collection of polygonal arcs and cycles can be folded so that all outermost arcs (not enclosed by other cycles) become straight and all outermost cycles become convex. A complementary result of this thesis is that once a cycle becomes convex, it can be folded into any other convex cycle with the same counterclockwise sequence of bar lengths. Together, these results show that the configuration space of all possible foldings of a planar arc or cycle linkage is connected. These results fall into the broader context of folding and unfolding k-dimensional objects in $n$-dimensional space, k <= n. Another contribution of this thesis is a survey of research in this field. The survey revolves around three principal aspects that have received extensive study: linkages in arbitrary dimensions (folding one-dimensional objects in two or more dimensions, including protein folding), paper folding (normally, folding two-dimensional objects in three dimensions), and folding and unfolding polyhedra (two-dimensional objects embedded in three-dimensional space)

Planar embeddings of graphs with specified edge lengths by Sergio Cabello ( )
3 editions published between 2004 and 2007 in English and held by 3 WorldCat member libraries worldwide
We consider the problem of finding a planar embedding of a (planar) graph with a prescribed Euclidean length on every edge. There has been substantial previous work on the problem without the planarity restrictions, which has close connections to rigidity theory, and where it is easy to see that the problem is NP-hard. In contrast, we show that the problem is tractable - indeed, solvable in linear time on a real RAM - for planar embeddings of planar 3-connected triangulations, even if the outer face is not a triangle. This result is essentially tight: the problem becomes NP-hard if we consider instead planar embeddings of planar 3-connected infinitesimally rigid graphs, a natural relaxation of triangulations in this context

Online routing in convex subdivisions ( )
2 editions published between 2000 and 2002 in English and held by 2 WorldCat member libraries worldwide
We consider online routing algorithms for finding paths between the vertices of plane graphs. We show (1) there exist a routing algorithm for arbitrary triangulations that has no memory and uses no randomization, (2) no equivalent result is špssible for convex subdivisions, (3) there is no competitive online routing algorithm under the Euclidean distance metric in arbitrary triangulations, and (4) there is no competitive online routing algorithm under the link distance metric even when the input graph is restricted to be a Delaunay, greedy, or minimum-weight triangulation
Resizable arrays in optimal time and space ( )
1 edition published in 1999 in English and held by 1 WorldCat member library worldwide
We present simple, practical and efficient data structures for the fundamental problem of maintaining a resizable one-dimensional array, $A[l...l+n-1]$, of fixed-size elements, as elements are added to or removed from one or both ends. Our structures are also support access to the element in position $i$. All operations are performed in constant time. The extra space (i.e., the space used past storing the $n$ current elements) is $O(\sqrt{n})$ at any point in time. This is shown to be within a constant factor of optimal, even if there are no constraints on the time. If desired, each memory block can be made to have size $2^k-c$ for a specified constant $c$, and hence the scheme works effectively with the buddy system. The data structures can be used to solve a variety of problems with optimal bounds on time and extra storage. This include stacks, queues, randomized queues, priority queues, and deques
