# What is Jigsaw Puzzles Solving

##### Jigsaw Puzzles Solving – A Technical Approach

Jigsaw puzzles are fun games that require assembling cut-out pieces of various shapes and colors to form an image. These puzzles come in different sizes, complexities, and styles, but their objective is the same - to challenge and entertain the players by testing their spatial awareness, problem-solving, and cognitive abilities. As much as jigsaw puzzles are enjoyable, they can be challenging. Some puzzles may take hours, days, or even weeks to complete, and without proper techniques, it can be frustrating and time-consuming.

##### Introduction to Jigsaw Puzzles Solving

The first step towards solving any jigsaw puzzle is to understand its objective. The puzzle pieces come in various shapes, colors, and designs that need to be matched correctly to form a coherent image. Depending on the difficulty of the puzzle, these pieces can range from a few tens to thousands, and the number of images to be formed can range from one to many. The puzzle is considered solved when all the pieces are correctly placed to form the correct image(s).

##### Basic Techniques for Solving Jigsaw Puzzles
• Sort and Organize the Pieces: Before starting to match the pieces, it is essential to sort and organize them according to their shape, edges, and colors. The sorting helps in creating groups of similar pieces that can be matched and arranged.
• Concentrate on Edges: The first step towards solving any jigsaw puzzle is to concentrate on the edges. The edges are easier to match as they have a definite shape and structure that can be easily recognized.
• Work on Small Sections: Instead of focusing on the entire puzzle, working on small sections of the image reduces the complexity and increases the speed of solving.
• Group Similar Colors and Patterns: Grouping similar colors and patterns helps in identifying the image parts that match and can be assembled together.
• Focus on the Image: The ultimate goal of the jigsaw puzzle is to form an image. Therefore, focusing on the image helps in recognizing the shapes, colors, and patterns that fit together.
##### Advanced Techniques for Solving Jigsaw Puzzles
• Work on One Color at a Time: If the puzzle has a predominant color, it is best to match the same color pieces first. This technique helps in creating smaller sections and identifying the missing parts.
• Use a Reference Image: Using a reference image helps in understanding the puzzle layout, shapes, and colors, making it easier to identify the missing pieces.
• Use the Trial and Error Method: If a piece's correct placement is not evident, placing it in different locations and checking if it fits can help identify its position.
• Use Shape and Pattern Recognition: Identifying the shapes and patterns that align or overlap helps in matching the pieces.
• Use Puzzle Solving Software: Using computer software designed explicitly for solving puzzles can significantly reduce the solving time and increase the accuracy.
##### Artificial Intelligence Techniques for Solving Jigsaw Puzzles

Jigsaw puzzle solving is not just a human skill. Computers, aided with artificial intelligence techniques, can solve puzzles as well. The approach for computer-based puzzle solving involves computer vision, pattern recognition, and optimization algorithms.

• Computer Vision: Computer vision involves image processing techniques that analyze the puzzle pieces' spatial arrangements and matches them with the reference image to identify their correct location.
• Pattern Recognition: Pattern recognition involves machine learning algorithms that identify and classify the pieces based on the shapes, patterns, and colors, reducing the complexity and increasing the speed and accuracy of solving.
• Optimization Algorithms: Optimization algorithms are used to optimize the solution by reducing the number of incorrect placements and enhancing the efficiency.
##### Conclusion

Jigsaw puzzles are fun games that require skills and techniques to solve. The basic techniques involve sorting and organizing, concentrating on the edges, working on small sections, grouping similar colors, and focusing on the image. Advanced techniques involve working on one color at a time, using a reference image, using trial and error methods, shape and pattern recognition, and using puzzle solving software. Artificial intelligence techniques involve computer vision, pattern recognition, and optimization algorithms that enhance the accuracy, speed, and efficiency of solving.
