VNS always clears all LocalImprovement operators when changing problem.
Added missing AlbaLambdaLocalImprovementOperator in VRP.

11:18 Changeset [11301] by pfleck

forgot to commit .csproj

11:12 Changeset [11300] by pfleck

Introduced ILocalImprovementAlgorithmOperator to separate single operators for local improvement and operator graphs/algorithms for local improvement.
This way the ILocalImprovementOperator does not have to specify a problem type and does not store a problem any more.

The LocalSearchImprovementOperator and SimulatedAnnealingImprovementOperator implement the new ILocalImprovementAlgorithmOperator as they represent an operator graph for local improvement.
The QAP and VRP local improvement operators implement the ILocalImprovementOperator which does not store a problem anymore.

The ILocalImprovementOperator specifies a ProblemType and stores a …

Renamed Cordeau instance files according to their instance provider class.

09:19 Changeset [11294] by pfleck

Renamed CordeauInstanceProvider to CordeauMDInstanceProvider and CordeauTWInstanceProvider to CordeauMDTWInstanceProvider as suggested by abeham.


13:23 Changeset [11293] by pfleck

Changed selection of neighborhood for shaking operator to a deterministic selection.
This way, neighborhoods won't be visited multiple times during an attempt to escape local optimum.

12:12 Changeset [11292] by pfleck

Split the CordeauInstanceProvider into 2 InstanceProvider which separates the MDCVRP and MDCVRPTW instances.

#1772: Fix calculation of successful offspring ratios in the GenealogyAnalyzer. Simplify cloning in the BeforeManipulatorOperator.

15:52 Changeset [11287] by pfleck

Fixed unit test for VRP instances.

14:20 Changeset [11286] by pfleck

Reverted parts of r10435 since the generic VRPInstanceProvider work accordingly after recent changes.

13:50 Changeset [11285] by pfleck

The ProblemInstanceProvider is now contravariant. Therefore the ProblemInstanceManager discovers all derivations of InstanceProvider<IVRPData>.

Note that there was a problem with covariant InstanceConsumers with the ProblemInstanceProviderView in the past (#1981).
Due to the fixes from #2110 this problem should not occur anymore.
