6.47.2 Constructor & Destructor Documentation

6.47.2.1 ABA_HISTORY::ABA_HISTORY (ABA_MASTER * master)

The constructor initializes a history table with 100 possible entries.

If this number is exceeded an automatic reallocation is performed.

Parameters:

master: A pointer to the corresponding master of the optimization.

6.47.2.2 virtual ABA_HISTORY::~ABA_HISTORY () [virtual]

The destructor.

6.47.3 Member Function Documentation

6.47.3.1 void ABA_HISTORY::update ()

Adds an additional line to the history table, primal bound, dual bound, and the time are taken from the corresponding master object. The history table is automatically reallocated if necessary.

Usually an explicit call to this function from an application class is not required since update() is automatically called if a new global primal or dual bound is found.
