P1: Consider the finite family of vectors V = {v1, . . . , vn} in Euclidean space Rk and positive integer m < n. Find a subset of vectors X of cardinality m such that the norm of the sum of the vectors from X is maximum.The second problem is connected in a signal search in...
previous algorithms took time O(n log n) or more per path. We improve this to constant time per path. A similar problem to the one studied here is that of finding the k minimum weight spanning trees in a graph. Recent algorithms for this problem [21, 22, 25] reduce it to fin...
Since it is NP-hard to find optimal $α$-edge separators for general graphs this means that it is NP-hard to find optimal vertex separators even when restricted to maximum degree 3 graphs. 展开 关键词: approximation algorithms combinatorial problems graph partitioning DOI: 10.1016/0020-0190(92)...
We improve previous algorithms for circumradius and variance based on Vor- onoi diagrams, which run in time O(n a+l) [2]. No previous bounds were known for the other problems. Table 1. New results for finding minimum measure k-point sets, given n points in the plane. (e is an ...
