<br><font size=2 face="sans-serif">Hello folks</font>
<br>
<br><font size=2 face="sans-serif">Want to share a couple thoughts on the
stochastic project and get your permission to begin entering code into
COIN.</font>
<br>
<br><font size=2 face="sans-serif">Our first objective will be to write
a simple set of interfaces that allow users to input scenario data, solve,
and extract solution data "by scenario". We'll derive an
OsiStochSolverInterface base class from OsiSolverInterface, and then provide
an implementation or two (OSLSE and CLP). </font>
<br>
<br><font size=2 face="sans-serif">Unless there are strenuous objections,
it seems to make sense to proceed as follows:</font>
<br><font size=2 face="sans-serif">1) introduce row/column labels into
the base OsiSolverInterface (defaults to string returning NULL) and develop
a bunch of sort/extract by label utilities.</font>
<br><font size=2 face="sans-serif">2) base the stochastic information management
in OsiStochSolverInterface on the label utilities (in stochastic programming
the labels correspond to nodes of the scenario tree).</font>
<br>
<br><font size=2 face="sans-serif">How do I get write permission?</font>
<br>
<br><font size=2 face="sans-serif">Best,</font>
