[Coin-discuss] re:Wuestions about bounds and model options

[Gabrielle A. Grün]

Hi Christian,

This should help you with your first question. Be watchful of the increments 
added.

/*! \brief Set cutoff bound on the objective function.

         When using strict comparison, the bound is adjusted by a tolerance 
to
         avoid accidentally cutting off the optimal solution.
         */
         void setCutoff(double value) ;
-----------------------------------------------------------------------------------

The following tweo functuions should be utiolized for  dealing with your 
second qtuestion.  Thqanks.

         /** Set the
         \link CbcModel::CbcMaximumSeconds maximum number of seconds 
\endlink
         desired.
         */
         inline bool setMaximumSeconds( double value) {
                  return setDblParam(CbcMaximumSeconds,value);


         /** Set the \link CbcModel::CbcAllowableFractionGap percentage 
allowable gap \endlink
         between the best known solution and the best possible solution.
         */
         inline bool setAllowablePercentageGap( double value) {
                  return setDblParam(CbcAllowableFractionGap,value*0.01);
         }
