WebJun 6, 2015 · The $\log n$ factor is part of the complexity for sorting the jobs by earliest due date which is $\mathcal{O}(n \log n)$. The difficulty to implement Moore's algorithm in $\mathcal{O}(n \log n)$ is the part in which you iterate over the jobs and move the so far longest job to the end of the schedule whenever a job is late. http://www.sba.oakland.edu/Faculty/Fliedner/POM%20521/PAC.doc
