2019 XCSP3 competition: main track (CSP and COP, sequential and parallel solvers): time to solve an instance

The figures below represent the number of instances that a given solver is able to solve in a given amount of time. The x axis represent the number of instances which the solver is able to solve when it is given y seconds for each instances.

These graphs are drawn for the different possible definitive answers in the different categories of benchmarks.
