A local search -approximation algorithm for the minimum -path partition problem
Yong Chen, Randy Goebel, Guohui Lin +5
Given a graph , the -path partition problem is to find a minimum collection of vertex-disjoint paths each of order at most to cover all the vertices of . It i…
Improved approximation algorithms for path vertex covers in regular graphs
An Zhang, Yong Chen, Zhi-Zhong Chen +1
Given a simple graph and a constant integer , the -path vertex cover problem ({\sc PVC}) asks for a minimum subset of vertices such that…
Approximation algorithms for the three-machine proportionate mixed shop scheduling
Longcheng Liu, Yong Chen, Jianming Dong +6
A mixed shop is a manufacturing infrastructure designed to process a mixture of a set of flow-shop jobs and a set of open-shop jobs. Mixed shops are in general much more complex to…
Approximation algorithms for two-machine flow-shop scheduling with a conflict graph
Yinhui Cai, Guangting Chen, Yong Chen +4
Path cover is a well-known intractable problem that finds a minimum number of vertex disjoint paths in a given graph to cover all the vertices. We show that a variant, where the ob…
