Detailed Description

class implements the storage of the solution history.

Definition at line 43 of file history.h.

Constructor & Destructor Documentation

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.

virtual ABA_HISTORY::~ABA_HISTORY

(

)

[virtual]

The destructor.

Member Function Documentation

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.

int ABA_HISTORY::size

(

)

const [inline, private]

Returns the length of the history table.

Definition at line 107 of file history.h.

void ABA_HISTORY::realloc

(

)

[private]

The function realloc() enlarges the history table by 100 components.

Friends And Related Function Documentation

ostream& operator<<	(	ostream &	out,
		const ABA_HISTORY &	rhs
	)			[friend]

The output operator.

Returns:

A reference to the output stream.

Parameters:

	out	The output stream.
	rhs	The solution history being output.
