At the 1997 MPS Symposium in Lausanne, there were two talks on secant/quasi-Newton methods. Just 25 years ago, this area was as hot as interior point methods have been recently. What caused this decline in activity? In my talk, I will use that question to motivate the evolution of quasi-Newton methods since the seminal paper of Bill Davidon was brought to light by Roger Fletcher and Mike Powell.
I promise not to offer yet another explanation of the superiority of BFGS over DFP or to bore the audience with arcane historical detail. I will offer some speculation on current directions in NLP.
