comment None of the NMinimize methods leads to the answers of the equation
@Daniel Thanks a lot. Yes, by adding Method->"EndomorphismMatrix" to the NSolve, I get the answers similar to the answers in Mathematica 9. But unfortunately, NMinimize can't approach to these sets of answers. May be I have missed some thing important.

comment None of the NMinimize methods leads to the answers of the equation
Thanks for the answer, but I need the equations to be very close to zero (at least of the order of 10^-16) or to be more precise my wish is to find parameters very close to what I found from NSolve with minimization. Just to remind, A1, A3, alpha1, alpha3, beta1 and beta3 are positive.

comment None of the NMinimize methods leads to the answers of the equation
@ Lotus For all the equations except eq5, eq6 and eq7, Eqs[1.2, 20][[1]] /. sol[[1]] is True. For eq5, eq6 and eq7, Eqs[1.2, 20][[7]] /. sol[[1]] is False but For example: Eqs[1.2, 20][[7, 1]] /. sol[[1]] is of the order 10^-18 which is not exactly zero but very close to it.

comment To simplify an expression further
ComplexExpand[expr] works and results in 0 in version 9.0.0.0, but in version 10.0.1.0, it doesn't yield zero.

@Lou thanks for your great help. The first link you referred to (mathematica.stackexchange.com/questions/20274/…), was exactly the one I searched for and didn't find. thanks.
