Constant-factor approximations for Capacitated Arc Routing without triangle inequality
Given an undirected graph with edge costs and edge demands, the Capacitated Arc Routing problem (CARP) asks for minimum-cost routes for equal-capacity vehicles so as to satisfy all demands. Constant-factor polynomial-time approximation algorithms were proposed for CARP with triangle inequality, while CARP was claimed to be NP-hard to approximate within any constant factor in general. Correcting...
متن کاملCapacitated Domination: Constant Factor Approximations for Planar Graphs
We consider the capacitated domination problem, which models a service-requirement assigning scenario and which is also a generalization of the dominating set problem. In this problem, we are given a graph with three parameters defined on the vertex set, which are cost, capacity, and demand. The objective of this problem is to compute a demand assignment of least cost, such that the demand of e...
متن کاملMultiobjective Capacitated Arc Routing Problem
The Capacitated Arc Routing Problem (CARP) is a very hard vehicle routing problem raised for instance by urban waste collection. In addition to the total route length (the only criterion minimized in the academic problem), waste management companies seek to minimize also the length of the longest trip. A bi-objective genetic algorithm is presented for this more realistic CARP, never studied bef...
متن کاملThe Capacitated Arc Routing Problem: Lower bounds
1997 ii ACKNOWLEDGEMENTS We would like mostly to thank Mr. Peter Keenan, who was as much a partner as a supervisor, for his invaluable time and erudite guidance during the summer. We must also pay tribute to our parents for their encouragement and support, not only for the duration of this dissertation, but throughout the year. ABSTRACT The Capacitated Arc Routing Problem is a NP-hard arc routi...
متن کاملThe Open Capacitated Arc Routing Problem
The Open Capacitated Arc Routing Problem (OCARP) is a NP-hard combinatorial optimization problem where, given an undirected graph, the objective is to find a minimum cost set of tours that services a subset of edges with positive demand under capacity constraints. This problem is related to the Capacitated Arc Routing Problem (CARP) but differs from it since OCARP does not consider a depot, and...
