public class LocalSearchOperator
extends BaseObject
The base class for all local search operators.
A local search operator is an object that defines the neighborhood of a
solution. In other words, a neighborhood is the set of solutions which can
be reached from a given solution using an operator.
The behavior of the LocalSearchOperator class is similar to iterators.
The operator is synchronized with an assignment (gives the
current values of the variables); this is done in the Start() method.
Then one can iterate over the neighbors using the MakeNextNeighbor method.
This method returns an assignment which represents the incremental changes
to the current solution. It also returns a second assignment representing
the changes to the last solution defined by the neighborhood operator; this
assignment is empty if the neighborhood operator cannot track this
information.
