Member Function Documentation

altAssignmentsToString()

String frodo2.benchmarks.auctions.xcsp.Relation.altAssignmentsToString ( )

private

This method transforms the mapping from utilities to the variable assignments yielding the corresponding utility into a string representation.

The syntax is as follows:
utility1: ass_1|ass_2|...|ass_n|utility2: ass_1|ass_2 etc.

Returns

String representation of alternative assignments

References alternativeAssignments.

Referenced by create().

create()

void frodo2.benchmarks.auctions.xcsp.Relation.create

(

)

This method adds the instance variables as attributes, so they are written to the 'relation' element in the XML output file.

To write the alternative assignments, another method is used

Here is the call graph for this function:

getNbTuples()

String frodo2.benchmarks.auctions.xcsp.Relation.getNbTuples ( Map< Double, List< String > > tuples )

private

Parameters

tuples

Mapping from values to assignments

Returns

Number of assignments found in the mapping

References nbTuples.

Referenced by Relation().
