Method Detail

getNextCandidate

public int getNextCandidate()

Description copied from class: ReductionHeuristic

Is used by the reduction agent steered by this heuristic to poll reduction candidates. This is the main interface for defining a heuristic, and it may depend on arbitrarily complex internal calculations. This method is abstract, so that every heuristic needs to implement it.

Specified by:

getNextCandidate in class ReductionHeuristic

Returns:

the next reduction candidate to be tried, -1 to terminate.

deliverCriticalClauses

public void deliverCriticalClauses(java.util.Set<java.lang.Integer> criticalClauses)

Description copied from class: ReductionHeuristic

Does nothing by default

Overrides:

deliverCriticalClauses in class ReductionHeuristic

getName

public java.lang.String getName()

Description copied from class: ReductionHeuristic

Defines the name of the heuristic as displayed in the reduction agent system.

Overrides:

getName in class ReductionHeuristic

Returns:

the name of the heuristic.
