Minimum Perimeter of a triangle - Mathematics Stack Exchange I have been playing the app Euclidea, I have been doing quite well but this one has me stumped "Construct a triangle whose perimeter is the minimum possible whose vertices lie on two side of the
combinatorics - Efficient computation of the minimum distance of a $q . . . In this way, you have to generate only a small fraction of all the codewords to find the minimum distance, and the idea can be generalized to any linear code The first step then is to find a covering of the coordinates with information sets
Determine if an edge appears in all Minimum Spanning Trees While this approach solves the problem, I'm looking for a way to decide whether some edge must appear in all minimum spanning trees without finding the minimum spanning trees
linear algebra - Setting the gradient to 0 gives a minimum . . . Therefore, the minimum x∗ = 0 x ∗ = 0 satisfies the two necessary conditions (as it must), but it does not satisfy the second order sufficient condition (and therefore to prove x∗ = 0 x ∗ = 0 is a minimum, you must resort to some other technique such as the nonnegativity of f f on R R as we mentioned previously)
