Tim,

Okay you also need to reset bounds

i.e.

for (k=0;k<10;k++)
        Solver->setColBounds(k,l[k],u[k]);

Osl modifies bounds as part of branch and bound.

**  Again this is a question which brings up a) should there be a branch 
and bound in Osi and b) We do need some coherent philosophy on what 
changes mean what.

By the way I modified Sbb to use a save solution but as Tobias mentions we 
now are running into Cgl conflicts.

I get a solution (actually the same as the original solution [0  0  0  1 0 
 0 
1  0  0  0]) with objective value 33 (also after 
addingSolver->setDblParam(OsiDualObjectiveLimit,1.0e50); ) . 

However there is a better solution [0  0  0  0  0  0  1  0  1  0] with 
objective value 75.
