算法1.14 Slow Tree Coloring树根涂为颜色0,并且将颜色0发送给所有的孩子节点节点v收到父亲节点的颜色cp; 决策自己的颜色为cv = 1 - cp 将cv发送给所有的孩子节点 Theorem 1.15 Algorithm1.14是正确的,并且算法的时间复杂度是树的高度。Definition 1.16(Log-Star)x<=2:log*x := 1 x > 2 : log...
Experimental AnalysisSummary: The DSATUR algorithm for vertex coloring is popular both in its heuristic and exact (branch-and-bound) forms. Common to the known public implementations of the exact algorithm is the use of adjacency matrices to store the adjacency relations; this influences the ...
给出了停机位分配问题顶点着色模型及其分解算法.通过改良一种时间冲突算法,构建了航班使用停机位的时间冲突集合.以"先到先服务"原则为基础,把停机位分配问题转化为顶点着色问题,并建立了相应模型.利用笔者独创的分解算法,停机位的作业能力可得到改善.算法的计算复杂度为O(n2).该算法的特点在于:1)将顶点、颜色划分为...

A New Vertex Coloring Algorithm Based on Variable Aaction-Set Learning Automata In this paper, we propose a learning automata-based iterative algorithm for approximating a near optimal solution to the vertex coloring problem. Vertex co... JA Torkestani,MR Meybodi - 《Computing & Informatics》 被...
Due to the presence of the coloring constraint, the feasible region can be broken into several zones that are separated from each other by infeasible regions in the search space. In this case, an algorithm searching only feasible solutions could be blocked in a particular feasible zone, thus ...

We propose three alternative Integer Linear Programming (ILP) formulations for WVCP: one is used to derive, dropping integrality requirement for the variables, a tight lower bound on the solution value, while a second one is used to derive a 2-phase heuristic algorithm, also embedding fast ...
