Organisation

AllProjects: open the vs solution containing all 4 projects.

Exact: code project of the BB

LBsrptImp: code project of the srptImp algorithm

sipsi: code project of Tanaka's algorithm

Tester1Ri: code project of the tester. (the solution file is inside)

Output: the exe file of all projects are copied to this folder. Use this folder to run any program. The dataset is also there. Extract the data first.

Parameters

To run the tester:

Put parameters in tester_config.txt, then run tester.exe tester_config.txt

The meaning of parameters can be found in tester_config.txt.

Or in Tester1Ri/testutils.h. Check the Config class.

The data.zip in Output folder should be decompressed first.

If need to regenerate data, verify the macro PMAX in tester.cpp.

To run the BB (chudc.exe) separately:

  • "chudc.exe [file=donnees.dat]"

  • the chudc.ini must exist. One parameter per line

  • Line 1: Search Strategy

    0, classical depth first 1, classical best first 2, classical breadth first 3, depth first memo 4, best first memo 5, breadth first memo 6, solution/lb memo (depth first)

  • Line 2: Clean Strategy. Put 3 to use LUFO.

  • Line 3: Dominance Strategy. Put 0 to disable or 12 to enable predictive dominance (by checking k-permutation)

To run the sipsi algorithm (sipsi.exe) separately:

  • "sipsi.exe input_file_name nbJobs"
