<div> Dear sir,</div>
<div> But why Blis can`t solve the same problem using best-first or best-estimate, while using depth can?</div>
<div> Also I have noticed that there are warnings while using best-first or best-estimate like bellow:</div>
<div> </div>
<div> WARNING: Subtree size is larger than message buffer size, will split it<br> </div>
<div> So does it because the Subtree is too large so causes the one of the process killed?</div>
<div> </div>
<div> I am really appreciate your timely reply!</div>
<div> Thank you very much!</div>
