Question

MultiStart Option

Hello! I'm trying to minimize a function with a built-in conjugate gradient/QuasiNewton method and would like to use a MultiStart option. However, it's not activated on my PC when I rightclick on the Minimize command. How can I make it work? Thanks in advance.

Ha Ha! Amazing. You are right, neither the Multistart or the Evolutionary options can be turned on. Even more amazing, I just checked and this was broken at least as far back as version 13. It works fine in version 11. I don't have version 12 installed so I can't check, but I suspect it's broken in that version too. I am very surprised that this has not come up before.

Edit: Maybe the worksheets posted here would help: http://communities.ptc.com/message/241809#241809
