Comparison of solvers Sugar v1.13+picosat and casper zito

Comparison of CPU time

Each point in the figure below represents the CPU time needed by the two solvers to solve a same instance. Points above the diagonal line represent instances where Sugar v1.13+picosat performs better. Points below the diagonal line represent instances where casper zito performs better.

'UNKNOWN' answers are considered as using the maximum allowed CPU time.
