Description of Results

All times are given in milliseconds.

Scores of 0, 1 and 2 are used in the tables rather than 0, 0.5 and 1.

A score of 0.0 indicates a worse answer in quality (worse objective, no proof of optimality, or no answer for satisfaction problems).
A score of 1.0 indicates a better solution in quality. When the quality is the same, the 1.0 purse is split with respect to time used.

If a promoted entry does not recognize an option (or states that it is just ignored), times and solutions from the previous category are used for scoring. The suffixes -fd, -free, -par, and -open (for the parallel portfolio solvers entered) at the end of the solver names indicate which configuration the solvers were run with.

The time limit includes both MiniZinc compilation and solving.

In the Status column:

• S indicates that a solution was found,
• C indicates that the search was complete,
• INC indicates an incorrect answer
• MZN indicates that flattening aborted (time-out or out-of-memory)
• UNK indicates that no answer was returned in the time limit or the solver aborted.
