I have already finished the initial implementation of AFT using L-BFGS, and it can produce the same result as the [R function | https://stat.ethz.ch/R-manual/R-devel/library/survival/html/survreg.html] test on the [Larynx cancer data | http://www.mcw.edu/FileLibrary/Groups/Biostatistics/Publicfiles/DataFromSection/DataFromSectionTXT/Data_from_section_1.8.txt]. I will submit the PR after correcting code format and adding more test cases. I think you can comment and review it in one or two days.
