New Functions

We implemented several new functions. Some of them might be also interesting for the users of ABACUS. For the detailed documentation we refer to the reference manual.

• ABA_BPRIOQUEUE::getMinKey()
• ABA_BHEAP::getMinKey()
• bool ABA_GLOBAL::isInteger(double x)
• In addition to the function

        void MASTER::initializePools(ABA_BUFFER<ABA_CONSTRAINT*> &constraints,
                                     ABA_BUFFER<ABA_VARIABLE*> &Variables,
                                     int varPoolSize,
                                     int cutPoolSize,
                                     bool dynamicCutPool = false);

  the function

         void MASTER::initializePools(ABA_BUFFER<ABA_CONSTRAINT*> &constraints,
                                      ABA_BUFFER<ABA_CONSTRAINT*> &cuts,
                                      ABA_BUFFER<ABA_VARIABLE*> &Variables,
                                      int varPoolSize,
                                      int cutPoolSize,
                                      bool dynamicCutPool = false);

  also allows the insertion of some initial cuts into the cut pool.
• Manipulators for setting the width and the precision of ABA_OSTREAM have been added that work like the corresponding manipulators of the class ostream.

        ABA_OSTREAM_MANIP_INT setWidth(int w);
        ABA_OSTREAM_MANIP_INT setPrecision(int p);

• ABA_OSTREAM::setFormatFlag(fmtflags)
• The objective function sense can be changed in the ABA_LP classes with the function

    void ABA_LP::sense(const ABA_OPTSENSE &newSense).

• The != operator is now available for the class ABA_STRING.
