MAX-CSP 2008 Competition: results by benchmark

Results by benchmark for category binary constraints in extension (2-ARY-EXT), subcategory academic problems

This page displays the results of the different solvers for each benchmark for category binary constraints in extension (2-ARY-EXT), subcategory academic problems

REMINDER

Keep in mind that the 'Best result' columns only provide the best result given by one of the solvers. This 'Best result' may be wrong in case of an UNSATISFIABLE or OPTIMUM FOUND answer (because there's no efficient way to check these answers).

Description of a cell contents:

Cell example	Meaning
Answer	Solver result
f=...	value of the objective function for the model reported by the solver
TT=...	Total Time (TT): this is the CPU time (in seconds) used by the solver until termination. This time is only meaningful for complete solvers because incomplete solvers will always run until they time out
T1=...	Time to get the best model (T1): this is the wall clock time (in seconds) ellapsed when the solver found its best model. This time is obtained from the 'o lines'. It is useful to compare both complete and incomplete solvers. It doesn't take into account the time to prove optimality of the solution.

Remember that CPU time and wall clock time are two very different notions. The CPU time represents the time during which the instructions of the solver were executed by the processor. The wall clock time represents how much time ellapsed on the clock. For a same event, the CPU time may be either smaller or greater than the wall clock time depending on the number of threads of execution and the number of processors.

Meaning of some abbreviations:

Abbreviation	Meaning
f=...	Value of the objective function
TO	Time Out
MO	Mem. Out (out of memory)

Meaning of the different colors:

Color	Meaning
text	the solver cannot handle this instance
text	the solver gave no answer
text	the solver could give an answer (SAT)
text	the solver gave a definitive answer (OPTIMUM FOUND or UNSAT)
text	the solver performed better than the other ones on that instance
text	the solver was ended by a signal
text	the solver gave an incomplete answer
text	the solver was disqualified in the category
text	the solver gave a wrong answer
