Hi,
I have struggled on this "bound optimization with equality constraint" by
using optim function for two days, but still fail to prepare a good input.
Can anyone help to prepare the input for my specific case? Many thanks.

Sorry for the unclear description in my last post. It is an error in my last
post, that x4 should be in the range of [-1, 0] as it is identical to x1.
Actually I think both "constraint" (for the requirement 1 and 2, so there
are only 9 variables) and "bounded" (for the requirement 3) opt are neede

Hi,
I am a beginner of R. There is a question about constraint minimization. A
function, y=f(x1,x2,x3x12), needs to be minimized. There are 3
requirements for the minimization:
(1) x2+x3+...+x12=1.5 (x1 is excluded);
(2) x1=x3=x4;
(3) x1, x3 and x5 are in the range of -1~0, respectively. T
