This page displays the results of the different solvers for each benchmark for category optimisation, big integers, linear constraints (OPT-BIGINT-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). |
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 |
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. |
Abbreviation | Meaning |
