Queue scheduling the Alan Cousins Telescope by Maartens, Deneys Sean

“…The next phase is the implementation of an automated scheduler that will generate a queue of valid observations for each night of observation. Queue scheduling algorithms are widely used in astronomy and the aim of this dissertation is to present a strawman scheduler that will generate the nightly observation queue. …”
