PB'12 competition: satisfaction and optimization track: results by benchmark

Results by benchmark for category optimisation, small integers, linear constraints (OPT-SMALLINT-LIN), subcategory Handmade, subsubcategory Course Assignment

This page displays the results of the different solvers for each benchmark for category optimisation, small integers, linear constraints (OPT-SMALLINT-LIN), subcategory Handmade, subsubcategory Course Assignment

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 exampleMeaning
AnswerSolver 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
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:

AbbreviationMeaning
f=...Value of the objective function
TOTime Out
MOMem. Out (out of memory)

Meaning of the different colors:

ColorMeaning
textthe solver cannot handle this instance
textthe solver gave no answer
textthe solver could give an answer (SAT)
textthe solver gave a definitive answer (OPTIMUM FOUND or UNSAT)
textthe solver performed better than the other ones on that instance (complete solvers point of view)
textthe solver performed better than the other ones on that instance (incomplete solvers point of view)
textthe solver was ended by a signal or other problem
textthe solver gave an incomplete answer
textthe solver gave a wrong answer
