Minimize returns vector with incorrect order

Minimize seems to be returning a vector ordered as if the input variables were sorted in alphabetical order, rather than in the order passed in. For example:

RVxayaxc = minimize( FAllaac(xa, ya, xc), [ixa,iya,ixc])
[ixa,iya,ixc], RVxayaxc

Gives the following. Note that the last two items are now reversed.

([107.048000000000,61.9900000000000,1.47700000000000],(107.075509604,1.47442809821,61.9967170491))

Is there any way to either avoid this or get the variable names for each item in the result?

Note that you are minimizing, and that the two are not *exactly* reversed, but the numbers are indeed different. Without knowing the function, it's hard to say whether this is actually wrong. Also, various algorithms may start at a point but then do some semi-random jumps to seek a minimum... Anyway, a little more detail is probably necessary for us to help. Thanks!
