In this chapter, we discuss three principal approaches to efficient determination of nearest neighbors: namely, using the triangle inequality when vectors are ordered with respect to their distances to one refe
Letandbe vectors. Then the triangle inequality is given by (1) Equivalently, forcomplex numbersand, (2) Geometrically, the right-hand part of the triangle inequality states that the sum of the lengths of any two sides of atriangleis greater than the length of the remaining side. So in ad...
The p-distance between two vectors, denoted ‖⋅‖p, is a general notion of distance, meaning that comparisons are non-negative, symmetric, satisfy the triangle inequality, and only equal zero when the inputs are identical. From: Progress in Energy and Combustion Science, 2023 ...
In fact, they are only equal if the two vectors are linearly dependent: There are several proofs of this inequality, which I encourage you to seek out if you are interested. But, in the totality of things, knowing this inequality is all that is really required for quantum computing. T...
Some reverses of the continuous triangle inequality for Bochner integral of nvector-valued functions in complex Hilbert spaces are given. Applications for ncomplex-valued functions are provided as well. 文档格式: .pdf 文档大小: 156.2K 文档页数: ...
Proof. For if |A,B|≤ |B,C|, we have |∠ACB|°≤ |∠BAC|° by 4.1.1(i) and this result. The triangle inequality. If A,B,C are non-collinear points, then |C,A| < |A,B| + |B,C|. Proof. Take a point D so that B∈ [A,D] and |B,D| = |B,C|. As C,B⊂...
for each k ∈ {1, . . . , n} . Now, the proof follows the same path as the one of Corollary 1 and we omit the details. 3. The Case of m Orthornormal Vectors In [1], the authors have proved the following reverse of the generalised triangle inequality in terms of orthornormal ...
The plane equations are written so that the normal vectors point outside the sphere-swept volume. 5 Knowing that the sphere and triangle are initially separated, the only ray-plane intersections we need consider are those for which the ray direction V and the plane normal form an obtuse angle...

We use a relaxation parameter β≥1 and require that the input instance is a complete graph G where the non-negative weight function c:E(G)→Q≥0 satisfies the relaxed triangle inequality c({u,w})≤β(c({u,v})+c({v,w})) for any three vertices u,v,w∈V(G). For approximation...
