<DIV><SPAN class=203515816-19022004><FONT face=Arial size=2>I am writing a web
interface for COIN, specifically for Clp and Sbb.</FONT></SPAN></DIV>
<DIV><SPAN class=203515816-19022004><FONT face=Arial size=2>I want to capture
output from these, especially from Sbb. The idea</FONT></SPAN></DIV>
<DIV><SPAN class=203515816-19022004><FONT face=Arial size=2>being folks could
"check progress" as the model runs.</FONT></SPAN></DIV>

<DIV><SPAN class=203515816-19022004><FONT face=Arial size=2>My first attempt was
to pause Sbb every x nodes, use methods </FONT></SPAN></DIV>
<DIV><SPAN class=203515816-19022004><FONT face=Arial size=2>to get best solution
and current objective, write these to a database, </FONT></SPAN></DIV>
<DIV><SPAN class=203515816-19022004><FONT face=Arial size=2>then restart.
Is </FONT></SPAN><SPAN class=203515816-19022004><FONT face=Arial size=2>it
possible to restart sbb after it times out or reaches</FONT></SPAN></DIV>

count?</FONT></SPAN></DIV>

<DIV><SPAN class=203515816-19022004><FONT face=Arial size=2>My next thought was
to just dump all Sbb output to a file, then read and</FONT></SPAN></DIV>
<DIV><SPAN class=203515816-19022004><FONT face=Arial size=2>display the output
as it runs. However, I am having major problems</FONT></SPAN></DIV>
<DIV><SPAN class=203515816-19022004><FONT face=Arial size=2>getting
output. When I run my application in the backgroud,
the</FONT></SPAN></DIV>

until Sbb terminates.</FONT></SPAN></DIV>
