Smooth Numbers and the Quadratic Sieve
When faced with a large number n to factor, what do you do first? You might say “Look at the last digit,” with the idea of cheaply pulling out possible factors of 2 and 5. Sure, and more generally, you can test for divisibility cheaply by all of the very small primes. So it may as well be assumed that the number n has no small prime factors, say below log n. Since it is also cheap to test for p...
متن کاملFactoring Large Numbers With a Quadratic Sieve
The quadratic sieve algorithm was used to factor a 47-digit number into primes. A comparison with Wagstaff's results using the continued fraction early abort algorithm suggests that QS should be faster than CFEA when the number being factored exceeds 60 digits (plus or minus ten or more digits, depending on details of the hardware and software).

this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...

تحقیق حاضر به بررسی کاربرد روش ژانر-محور را در محیط آموزش زبان عمومی می پردازد.روش ژانر-محور به زبان آموزان کمک میکند که در زمینه خوانش پیشرفت کنند. بعضی از محققین معتقد اند که روش تدریس ژانر-محور به تدریج به زبان آموزان کمک می کند تا در درک ژانر های مختلف مهارت یابند (هایلند 2004).همچنین امروزه توجه روز افزونی به اهمیت استفاده از ادبیات در برنامه آموزشی زبان انگلیسی (esl/efl ) شده است. زمانی ک...
