[Coin-discuss] OsiStochSolverInterface -- initial objective and outline

[Alan King]

Hello folks

Want to share a couple thoughts on the stochastic project and get your 
permission to begin entering code into COIN.

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). 

Unless there are strenuous objections, it seems to make sense to proceed 
as follows:
1) introduce row/column labels into the base OsiSolverInterface (defaults 
to string returning NULL) and develop a bunch of sort/extract by label 
utilities.
2) base the stochastic information management in OsiStochSolverInterface 
on the label utilities (in stochastic programming the labels correspond to 
nodes of the scenario tree).

How do I get write permission?

Best,
Alan
