{"product_id":"natural-algorithms-von-joshua-arulanandham","title":"Natural Algorithms","description":"\u003cp\u003eI explore simple natural physical systems that exhibit useful, interesting computational effects. I view such physical systems as specialized ¿computers¿\/natural¿computers. These natural¿computers (physical systems), as they evolve in phase space, can be seen as performing a computation or executing a natural algorithm to solve a specific problem. In particular, I consider physical systems that apparently ¿solve¿ problems that are hard to solve by using conventional computers. I view the physical systems themselves¿not their numerical simulations¿as computers.    I discuss three main ideas: A gravity powered ¿computer¿¿constructed out of beads and rods of an abacus¿that can perform data processing tasks like sorting, searching, etc. on an unsorted database; Bilateral Computing paradigm for the construction of natural physical computing devices, whose operation blurs the distinction between computing and inverting a mathematical function; Balance Machine, a generic natural computational model that is shown to be computationally universal.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783845444857\"\u003e\u003ch3\u003eExploring simple natural physical systems that can compute\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783845444857","offer_id":39494595215453,"sku":"9783845444857","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ba94bd45-fb18-4fe3-8048-a10ba4e13462.jpg?v=1773472433","url":"https:\/\/shop.autorenwelt.de\/en\/products\/natural-algorithms-von-joshua-arulanandham","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
