Abstract
Massive observational surveys are becoming increasingly important in astronomical and cosmographic research. It has long been known that the key to a number of pressing astrophysical and cosmological problems is large-scale deep spectroscopic surveys, mainly using large telescopes. In order to maximize the utilization of several thousands of fiber positioners, to achieve enhanced performance, and to save valuable observational time, we propose a fast algorithm which takes the priority of targets and target completeness into consideration. Through simulations based on sets of randomly distributed catalogs and observation scheme of LAMOST, a higher target completeness is achieved compared with the draining algorithm.
