Euler bricks {a,b,c} and Euler quadruples {a,b,c,d} Hello all, I. The "Euler brick" is well-known. These are triples (a,b,c) such that, a^2+b^2 = x^2 a^2+c^2 = y^2 b^2+c^2 = z^2 all in positive integers. II. Euler also considered quadruples (a,b,c,d) such that, a^2+b^2+c^2 = x^2 a^2+b^2+d^2 = y^2 a^2+c^2+d^2 = z^2 b^2+c^2+d^2 = t^2 Interestingly,... 13 Aug 2010 16:52

Linear program with higher order non-linear constaints??? Hi, I am not sure whether I have posted the question on the right place or not as I was unable to find the optimization forum. I want to solve a linear objective function, with some linear constraints and one higher order non-linear (not quadratic, it Lp-norm) constraint. I know that Lp-norm constraint can be ... 13 Aug 2010 15:46

abramowitz book, is it still relevant to today's needs? I checked the last printing of Abramowitz and Stegun's handbook of mathematical functions, with formulas, graphs and mathematical table; the last printing, the 10th precisely, was in 1972.
