public class CPProfiler
extends SearchViz

A search monitor to send data to cp-profiler. It enables to profile and to visualize Constraint Programming. An installation is needed and is described here. This monitor relies on its java integration.

Note that CPProfiler is Closeable and can be used as follow:

 
 Model model = ProblemMaker.makeCostasArrays(7);
  try (CPProfiler profiler = new CPProfiler(model)) {
      while (model.getSolver().solve()) ;
      out.println(model.getSolver().getSolutionCount());
 }

Constructor Detail

CPProfiler

public CPProfiler(Solver aSolver,
                  boolean sendDomain)

Active connection to cp-profiler. This requires cp-profiler to be installed and launched before.

Parameters:

aSolver - solver to observe resolution

sendDomain - set to true to send domain into 'info' field (beware, it can increase the memory consumption and slow down the overall execution), set to false otherwise.
