Divisibility question.

<t>Consider all the integers generated by reordering the 9 digit number 123456789. Let's denote this set by S. Clearly, |S| = 9!.So, there must exist k in {0, 1, 2, 3, 4, 5, 6} such that S_k = { x in S such that x mod 7 = k } has more than 9!/7 elements. In other words, |S_k| = 9!/7 > 50000.All the ...

A Question About Optimization

<t>Recently I have been working on an optimization problem which in essence is to find the minimal value ofF(x) = f(x) + max(g_1(x), g_2(x), g_3(x), ...g_n(x))under the constraints thatx >= 0,Ax <= b,where x, b vector, A matrix. f, g_1 ..., g_n are linear functions.In other words, this is a classic ...

E[m/M]

shinichivn's method is cool. Say M_k is the k-th biggest value of X_1, X_2 ...X_n. One can use shinichivn's method to calculate E(M_k) easily!

.101001000100001000001000000100.................

Let a = .101001000100001000001000000100..............................Clearly, {Na} (the decimal part of Na) for N = 1,2,3,4... is dense in [0,1]. Hence, a is irrational.
