Hi all!

I'm using NMinimize as an alternative to Minimize for a non-linear constrained optimization problem. I have the following question regarding its warnings, more exactly how much error could be in the output if I get the followings.

1. ,,NMinimize was unable to generate any initial points satisfying the \
inequality constraints ... The initial region specified may not contain any feasible points. \
Changing the initial region or specifying explicit initial points may \
provide a better solution.''

Is this warning message similar to the next one which is returned by Minimize

,,Minimize::wksol: Warning: There is no minimum in the region in which the objective \
function is defined and the constraints are satisfied; returning a \
result on the boundary.''

2. Failed to converge to the requested accuracy or precision within 100 iterations.

I mention that the result obtained is exactly what I'm expecting, except some decimals.

Thank you very much!
