In general they should be slightly different.

※ 引述《mercurial (多变)》之铭言：
: Is it possible that I get different result with hw5(without decomposition)?
: I think it is, because hw5 didn't consider the constrant of y*alpha=0
: however, hw7 with that constraint should get worse optimal value
: but my hw7 optimal value is less than hw5..
: and the alpha is still satisify all the constrants...
: how do you think?? am I misunderstand anything?
