A Hybrid Genetic Algorithm for the Target Visitation Problem
نویسندگان
چکیده
In this paper we consider the problem of determining an optimal path for an unmanned aerial vehicle which needs to visit multiple targets. The objective is to minimize the travel distance while maximizing the utility of the visitation order. This is known as the TARGET VISITATION PROBLEM and has several applications including combat search and rescue, environmental assessment, and disaster relief. First, we provide a mathematical model based on integer linear programming and prove that the problem is NP-complete. Then we describe the implementation of a genetic algorithm for finding approximate solutions. The heuristic is then hybridized by the implementation of a local search procedure. Numerical results are presented demonstrating the effectiveness of the proposed procedure.

An Efficient Target Tracking Algorithm Based on Particle Filter and Genetic Algorithm
In this paper, we propose an efficient hybrid Particle Filter (PF) algorithm for video tracking by employing a genetic algorithm to solve the sample impoverishment problem. In the presented method, the object to be tracked is selected by a rectangular window inside which a few numbers of particles are scattered. The particles’ weights are calculated based on the similarity between feature vecto...

This paper considers a bi-objective scheduling problem in a flexible manufacturing cell (FMC) which minimizes the maximum completion time (i.e., makespan) and maximum tardiness simultaneously. A new mathematical model is considered to reflect all aspect of the manufacturing cell. This type of scheduling problem is known to be NP-hard. To cope with the complexity of such a hard problem, a genet...
