Camponogara and Shima (2010) developed an ε-approximation algorithm (FPTAS) for the mobile agent routing problem in which a benefit function determines how visits to different sites contribute to the agent's mission. The benefit is to be maximized under a time constraint. They reduced the problem to the constrained longest-path problem in a graph. In this(More)
The aim of this paper is to develop an improved polynomial-time approximation algorithm belonging to the family of the fully polynomial time approximation schemes (FPTAS), for an ancient scheduling problem with deadlines. The algorithm permits to answer a question posed more than three decades ago in Gens & Levner (1981): “Can an(More)
—Mobile agents are autonomous programs that may be dispatched through computer networks. Using a mobile agent is a potentially efficient method to perform transactions and retrieve information in networks. Unknown congestion in a network causes uncertainty in the routing times of mobile agents so the routing of mobile agents cannot rely solely on the(More)
