Problema a aparut in MIT Technology Review in Noiembrie 2012 si a avut 20 de rezolvari, toate insa gasite cu ajutorul unui program. Pana azi nu a reusit nimeni sa-i gaseasca o rezolvare deductiva.
Ce se cere , e simplu, sa se gaseasca numerele de sub semnul intrebarii. Conditia este doar ca produsele partiale sa aiba 5 si respectiv 4 cifre, fara 0 la inceput, fireste.
Solutia e unica. Se poate folosi program, asta ar fi primul pas. Al doilea... :D... e cineva atata de istet incat sa dea o rezolvare deductiva ? |
