title: Do Google Optimization Tools support Soft Constraints?
body: <p>I was wondering if anyone familiar with Google Optimization tools can address this. I was looking at the Google <a href="https://developers.google.com/optimization/scheduling/employee_scheduling" rel="nofollow noreferrer">examples</a> both employee scheduling and N-queens. Both example seem to have the optimizer running only on hard constraints (e.g. this must be the case) but doesn't seem to solve (this is the preferred but not required). Is there support for soft-constraints? Or is the only implementation of soft constraints at this time <a href="https://www.optaplanner.org/" rel="nofollow noreferrer">optaplanner</a>?</p>
  
  <p>I'm not opposed to optaplanner. It just will require a lot more effort to learn enough java and the "drools" syntax used. </p>
