An Optimisation with an Orthogonality Constraint
I have a simple-looking optimisation as follows: min ||PAP' - B||^2_F s.t. P'P = I where " ' " means transpose, A, B, P are real n*n matrices, || . ||_F is the Frobenius norm, A,B are symmetric positive semi-definite matrices, and P is an unknown orthogonal matrix. By introducing Langrange multipliers, differ... 26 Jan 2010 10:57

dissections 1+2=sqrt(5) of polyominoes
Hi all. On the newsgroup it.hobby.enigmi, Livio Zucca proposed to dissect a polyomino of side 1 and its double of side 2 (here with side I mean the side of the small squares which form it) and rearrange the pieces into a similar polyomino of side sqrt(5). He also proposed the problem of dissecting a pentomino an... 26 Jan 2010 07:39
