Detailed Description

This variable ordering heuristic should select the variables with the highest/lowest conflict count (over all their values).

Member Enumeration Documentation

enum Impact::Preference

Enumeration values: Minimum  Prefer the variables with the minimum impact. Maximum  Prefer the variables with the maximum impact.

Constructor & Destructor Documentation

Impact::Impact (  Decomposition &  decomposition, const vector< pair< double, double > > &  intervals, double  quality = 1, Preference  preference = Maximum, bool  dynamic = false )

Constructor. Parameters: decomposition  the decomposition using this heuristic. intervals  the depth intervals where the heuristic is active; if no intervals are given, the heuristic is always active. quality  the heuristic's quality, in the [0-1] range. preference  the impact preference. dynamic  `true' if the total conflict counts are to be computed dynamically, `false' otherwise.

Member Function Documentation

void Impact::select (  vlist_type &  selectable, vlist_type &  selected )  [virtual]

Select the variables with the best impact, according to the current preference. Parameters: selectable  the list of variables to select from. selected  selected variables should be moved here. Implements VariableOH.
