{"product_id":"9781533285942","title":"Sudoku 200 Challenging Puzzles With Answers Book 6: 200 Challenging Sudoku Puzzles With Answers","description":"Solving a Sudoku game is a combinatorial task of intermediate complexity. The g?nerai problem of filling in an incompl?te n 2 x n 2 grid with n x n subgrids belongs to the class of NP-complete problems. Th?se problems are conjectured to increase in computational complexity at an exponential rate in n. Nonetheless, a well planned exhaustive search can work quite well for a low value of n such as 9. For larger values of n, brute force, no matter how cleverly executed, is simply not an option. In contrast, simulated annealing and alternating projections may yield good approximate solutions and partially salvage the situation.\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e• \u003cb\u003eAuthor: \u003c\/b\u003eChamp Lopez\u003c\/li\u003e\n\u003cli\u003e• \u003cb\u003ePublisher: \u003c\/b\u003eCreateSpace Independent Publishing Platform\u003c\/li\u003e\n\u003cli\u003e• \u003cb\u003ePublication Date: \u003c\/b\u003eMay 16, 2016\u003c\/li\u003e\n\u003cli\u003e• \u003cb\u003eNumber of Pages: \u003c\/b\u003e102 pages\u003c\/li\u003e\n\u003cli\u003e• \u003cb\u003eLanguage: \u003c\/b\u003eEnglish\u003c\/li\u003e\n\u003cli\u003e• \u003cb\u003eBinding: \u003c\/b\u003ePaperback\u003c\/li\u003e\n\u003cli\u003e• \u003cb\u003eISBN-10: \u003c\/b\u003e1533285942\u003c\/li\u003e\n\u003cli\u003e• \u003cb\u003eISBN-13: \u003c\/b\u003e9781533285942\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CreateSpace Independent Publishing Platform","offers":[{"title":"Default Title","offer_id":50367815352625,"sku":"9781533285942","price":13.4,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0798\/8215\/8385\/files\/9781533285942__83579.jpg?v=1732531897","url":"https:\/\/www.recomparo.com\/products\/9781533285942","provider":"ReComparo.com","version":"1.0","type":"link"}
