#2208

  • Uses average distance as maximum distance when interpreting VRP as OP.

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

11:18 Changeset [11301] by pfleck

#2208
forgot to commit .csproj

11:12 Changeset [11300] by pfleck

#2232
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 …

#2226
Renamed Cordeau instance files according to their instance provider class.

09:55 Changeset [11295] by pfleck

#2226:

09:19 Changeset [11294] by pfleck

16:05 Changeset [11288] by bburlacu

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

15:52 Changeset [11287] by pfleck

#2225
Fixed unit test for VRP instances.

14:20 Changeset [11286] by pfleck

#2225
Reverted parts of r10435 since the generic VRPInstanceProvider work accordingly after recent changes.

13:50 Changeset [11285] by pfleck

#2225
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.
