A Binary puzzle is a Sudoku-like puzzle with values in each cell taken from the set {0, 1}. Let n ≥ 4 be an even integer, a solved binary puzzle is an n × n binary array that satisfies the following conditions: (1) no three consecutive ones and no three consecutive zeros in each row and each column; (2) the number of ones and zeros must be equal in each row and in each column; (3) there can be ...

In this work I study a modified Tower of Hanoi puzzle, which I term Magnetic Tower of Hanoi (MToH). The original Tower of Hanoi puzzle, invented by the French mathematician Edouard Lucas in 1883, spans "base 2". That is – the number of moves of disk number k is 2^(k-1), and the total number of moves required to solve the puzzle with N disks is 2^N 1. In the MToH puzzle, each disk has two distin...

The jigsaw puzzle assembly problem is significant in that it can be applied to diverse areas such as repair of broken objects , restoration of archaeological findings, molecular docking problem for drug design, etc. This paper describes a new pictorial jigsaw puzzle solver which, in contrast to previous apictorial jigsaw puzzle solvers, uses chromatic information as well as geometric shape. We ...

Self-assembly processes and subsequent photo-cross-linking were used to generate cross-linked, ordered microporous structures on the surfaces of well defined four-arm star-shaped poly(D,L-lactide) (PDLLA) thin films. The four-arm star-shaped PDLLAs were synthesized using an ethoxylated pentaerythritol initiator. Solutions of the PDLLAs were cast in a humid environment, and upon solvent evaporat...

Speech can lead to increased performance in computer-based problem solving. Studies of complex interaction styles — such as command-line or system-delayed interaction — have found that complex interaction styles can lead to savings in the number of actions users take to reach a solution for certain tasks compared with direct manipulation. Speech can be viewed a complex interaction style because...

In this paper, we propose a new, nonparallelizable verification-efficient client puzzle. Our puzzle is based on repeated-squaring and enables efficient verification of the puzzle solution that is reported by the client (prover). Client puzzles based on repeated-squaring were first proposed by Rivest et al. in [1] and constitute one of the first examples of nonparallelizable puzzles. The main dr...

Introduction: The purpose of beading & boxing of an impression is to obtain an accurate cast with proper border & base thickness for fabrication of restorations. Beading is the protection of the formed border thickness of the final impressions & Boxing of an impression is building up vertical walls around it. Aim: The purpose of this hybrid technique of beading and boxing is to produce a smooth...

Consider the problem of guiding a vehicle that has to move within severe spatial constraints. It may be a car that is getting into or out of a busy parking lot, where it has to cooperate with the movements of other cars, possibly even in the style of a 15-puzzle. It may also be a helicopter that moves near buildings or other obstacles, and that is required to maintain line of sight to some obje...
