Choco solver logging

I'm trying the Choco solver (version 4.10.1) for the first time, and I don't know how to enable logging for the solver. I've added slf4j-log4j12 dependency and a log4j.properties file.

For older Choco (e.g. v3) versions, the doc mentioned some stuff about this. for example some Chatterbox class, that is no longer present.

Any ideas how to enable some logging for the solver?

Solution

  • Guys from Chocoteam helped. The methods are 

    solver.showXXX()

    E.g. showDecisions(), showSolutions(), etc. and also printStatistics()

    See javadoc for more information.
