Method Detail

getAllCordeauP

public static Collection<BenchmarkInstance> getAllCordeauP(String inputFolder)

Returns a collection of BenchmarkInstance which are Cordeau's p instances.

Note that this assumes that within the folder 'inputFolder' 23 p-instances are located with their original name, i.e. p01,p02,...,p23.

It also assumes that solution files are also located in inputFolder ending with .res

Parameters:

inputFolder - where cordeau's p instances are located. It must end without '/' such as instances/cordeau.

Returns:

a collection of BenchmarkInstance

getAllCordeauPR

public static Collection<BenchmarkInstance> getAllCordeauPR(String inputFolder)

Returns a collection of BenchmarkInstance which are Cordeau's pr instances.

Note that this assumes that within the folder 'inputFolder' 10 p-instances are located with their original name, i.e. pr01,pr02,...,pr10.

It also assumes that solution files are also located in inputFolder ending with .res

Parameters:

inputFolder -

inputFolder - where cordeau's pr instances are located. It must end without '/' such as instances/cordeau.

Returns:

a collection of BenchmarkInstance

getAllChristofides

public static Collection<BenchmarkInstance> getAllChristofides(String inputFolder)

Returns a collection of BenchmarkInstance which are Christofides vrpnc instances.

Note that this assumes that within the folder 'inputFolder' 14 vrpnc-instances are located with their original name, i.e. vrpnc1,vrpnc2,...,vrpnc14.

Parameters:

inputFolder - where christofides vrpnc instances are located. It must end without '/' such as instances/christofides.

Returns:

a collection of BenchmarkInstance

getAllSolomonC1

public static Collection<BenchmarkInstance> getAllSolomonC1(String inputFolder)

Returns a collection of BenchmarkInstance which are Solomon instances.

Note that this assumes that within the folder 'inputFolder' 9 C1-instances are located with their original name, i.e. C101.txt,C102.txt,...,C109.txt.

Note that unlike the original problems, a fixed-cost value of 1000 is set for each employed vehicle.

Parameters:

inputFolder - where solomon C1 instances are located. It must end without '/' such as instances/solomon.

Returns:

a collection of BenchmarkInstance

getAllSolomonC2

public static Collection<BenchmarkInstance> getAllSolomonC2(String inputFolder)

Returns a collection of BenchmarkInstance which are Solomon instances.

Note that this assumes that within the folder 'inputFolder' 8 C2-instances are located with their original name, i.e. C201.txt,C202.txt,...,C208.txt.

Note that unlike the original problems, a fixed-cost value of 1000 is set for each employed vehicle.

Parameters:

inputFolder - where solomon C2 instances are located. It must end without '/' such as instances/solomon.

Returns:

a collection of BenchmarkInstance

getAllSolomonR1

public static Collection<BenchmarkInstance> getAllSolomonR1(String inputFolder)

Returns a collection of BenchmarkInstance which are Solomon instances.

Note that this assumes that within the folder 'inputFolder' 12 R1-instances are located with their original name, i.e. R101.txt,R102.txt,...,R112.txt.

Note that unlike the original problems, a fixed-cost value of 1000 is set for each employed vehicle.

Parameters:
