An Approximation Algorithm for the Capacitated Arc Routing Problem
In this paper we consider approximation of the Capacitated Arc Routing Problem, which is the problem of servicing a set of edges in a graph using a fleet of capacity constrained vehicles. We present a 7 3 2 W approximation algorithm for the problem and prove that this algorithm outperforms the only existing approximation algorithm for the problem. Furthermore, we give computational results show...
متن کاملBRKGA Algorithm for the Capacitated Arc Routing Problem
We propose a new algorithm for the Capacitated Arc Routing Problem (CARP). Our motivation to deal with this problem is related to its application in several real world scenarios such as street sweeping, urban waste collection and electric meter reading just to mention a few. Based on BRKGA metaheuristic, our algorithm introduces a new random key encoding for CARP, mutation to random keys string...
متن کاملA parameterized approximation algorithm for the mixed and windy capacitated arc routing problem: Theory and experiments
We prove that any polynomial-time α(n)-approximation algorithm for the n-vertex metric asymmetric Traveling Salesperson Problem yields a polynomial-time O(α(C))-approximation algorithm for the mixed and windy Capacitated Arc Routing Problem, where C is the number of weakly connected components in the subgraph induced by the positive-demand arcs—a small number in many applications. In conjunctio...
متن کاملImmune clonal selection algorithm for capacitated arc routing problem
In existing metaheuristics for solving the capacitated arc routing problem, traversal local search operators are often used to explore neighbors of the current solutions. This mechanism is beneficial for finding high-quality solutions; however, it entails a large number of function evaluations, causing high computational complexity. Hence, there is a need to further enhance the efficiency of su...
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...
