[Scip] first dual bound

[Tuomo Takkula]

Hi,

how can I get hold of the first "dualbound" value that Scip prints during it's run, that is, the 
dual bound after presolving. My first attempts were

(1) Call SCIPpresolve, and then try one of

SCIPgetLPObjval(scip)
SCIPgetLPRootObjval(scip)
SCIPgetLPColumnObjval(scip)
SCIPgetLocalDualbound(scip)
SCIPgetLocalLowerbound(scip)
SCIPgetDualboundRoot(scip)
SCIPgetDualbound(scip)
SCIPgetLowerbound(scip)
SCIPgetLowerboundRoot(scip)

(2) Call SCIPpresolve, solve one node and try one of the methods in (1).

Both attempts were in vain though. The only nontrivial value was the first one (LP bound), and this 
was still far worse than the first "dualbound" output.


So, how should I do it?


Best regards
Tuomo
