Design and analysis of vertex covered problem by greedy algorithm
摘要
Abstract
As the relative rate η≤2 between such approximate solution andexact solution, this paper introduces another greedy algorithm to solve the problem,and proves the relative rate η≤H(d), H(d)= ∑1/j (j=(1, 2, ……, d), where d is the maximal degree of vertex in the graph. Therefore,greedy algorithm has improved the accuracy of solution evidently while d≤3.关键词
