We present jigsaw parallelism constraints, a flexible formal tool for replacing parts of trees with other trees. Jigsaw constraints extend the Constraint Language for Lambda Structures, a language used in underspecified semantics to declaratively describe scope, ellipsis, and their interaction, and can be used to improve the coverage of ellipses represented by CLLS.

In this report we present our work on designing and implementing a mobile phone application that helps people solve jigsaw puzzles by locating the image of a single patch on the complete picture. Details of the algorithm and implementation are discussed and test results are presented. Keywords-component; Jigsaw Puzzle; Mobile Application; Template Matching; Image Segmentation; SURF; RANSAC

This study used action research (classroom research) in two rounds. Each round consists of four stages, namely: design, activity and observation, reflection, revision. The formulation the problem this is: Can use Jigsaw type cooperative learning model improve science outcomes for fourth grade students at SD Negeri 193 Palembang? purpose was to find out increase Palembang through application a j...

Sex differences are consistently reported in different visuospatial tasks with men usually performing better in mental rotation tests while women are better on tests for memory of object locations. In the present study, we investigated sex differences in solving jigsaw puzzles in children. In total 22 boys and 24 girls were tested using custom build tablet application representing a jigsaw puzz...

Neurons have been found in the primate brain that respond to objects in specific locations in hand-centered coordinates. A key theoretical challenge is to explain how such hand-centered neuronal responses may develop through visual experience. In this paper we show how hand-centered visual receptive fields can develop using an artificial neural network model, VisNet, of the primate visual syste...

Most jigsaw puzzles that are available today consist of several 100 pieces of a single image, and can take several hours to solve. This project proposes to solve the puzzle simply by using a picture of all of the pieces, and an image of the final solution.

1.1. Jigsaw puzzles reimagined. I will describe jigsaw puzzles that are somewhat different to the familiar kind. A box, shown in Figure 1, contains an infinite supply of the three types of pieces pictured on its side: one five–sided and two four–sided, their edges coloured green, blue and red and directed by arrows. It also holds an infinite supply of red, green and blue rods, again directed by...

We consider the problem of reconstructing graphs or labeled graphs from neighborhoods of a given radius r. Special instances of this problem include DNA shotgun assembly, neural network reconstruction, and assembling random jigsaw puzzles. We provide some necessary and some sufficient conditions for correct recovery both in combinatorial terms and for some generative models including random lab...

We prove the computational intractability of rotating and placing n square tiles into a 1×n array such that adjacent tiles are compatible—either equal edge colors, as in edge-matching puzzles, or matching tab/pocket shapes, as in jigsaw puzzles. Beyond basic NP-hardness, we prove that it is NP-hard even to approximately maximize the number of placed tiles (allowing blanks), while satisfying the...
