1. (a) Use the Euclidean Algorithm to find the greatest common divisor of 44 and 17. The Euclidean Algorithm yields: 44 = 2·17+10 17 = 1·10+7 10 = 1·7+3 7 = 2·3+1. Therefore the greatest common divisor of 44 and 17 is 1 . (b) Find whole numbers x and y so that 44x+17y = 1 with x > 10.
3.1] A Euclidean distance matrix, an EDM in RN×N +, is an exhaustive table of distance-square dij between points taken by pair from a list of N points {xℓ, ℓ=1...N} in Rn; the squared metric, the measure of distance-square: dij = kxi − xjk 2 2, hxi − xj, xi − xji (1037)
The cone of Euclidean distance matrices and its geometry is described in, for example, [11, 59, 71, 111, 112]. Using semidefinite optimization to solve Euclidean distance matrix problems is studied in [2, 4]. Further theoretical results are given in [10, 13].
Given a partially-specified symmetric matrix A with zero diagonal, the Euclidean distance matrix completion problem (EDMCP) is to determine the unspecified entries to make A a Euclidean distance matrix. We survey three different approaches to solving the EDMCP.

How do we reconstruct the molecule? Density map and structure of a molecule [10.7554/elife.01345] Euclidean Distance Matrix. Consider a set of n points X 2 Rd n, edm(X) contains the squared distances between the points, Equivalently, edm(X) = 1 diag(XTX)T. 2XTX + diag(XTX)1T. EDM properties: rank and essential uniqueness.
For examples of applications requiring solutions of EDM problems with different complications, see Figure 1. There are two fundamental problems associated with distance geometry [10]: 1) given a matrix, determine whether it is an EDM and 2) given a possibly incomplete set of distances, determine
