Parameterized algorithms and complexity for the traveling purchaser problem and its variants Autor Xiao, Mingyu, Zhang, Jianan, Lin, Weibo

“…), we study TPP and its variants from the view of parameterized complexity. We show that TPP and some variants are fixed-parameter tractable by taking the number k of products or the number m of suppliers as the parameter, and W[2]-hard by taking the number q of visited suppliers as the parameter. Furthermore, we implement some of our fixed-parameter tractable algorithms to show that they are practically effective when the parameters are not very large…”
