print(ScoreAnalysis): make it easy to analyze a score during POC #76

Closed ge0ffrey closed 2 days ago

ge0ffrey commented 3 weeks ago

print() is great during POC ScoreAnalysis and ConstraintAnalysis should work will it wel

Blocked by https://github.com/TimefoldAI/timefold-solver/issues/883 This should work well in Java too.

Current status:

print(score_analysis)
<timefold.solver.score._score_analysis.ScoreAnalysis object at 0x1049ff350>

    print(score_analysis.constraint_map)

{ConstraintRef(package_name='org.jpyinterpreter.user.employee_scheduling.domain', constraint_name='Desired day for employee'): <timefold.solver.score._score_analysis.ConstraintAnalysis object at 0x1049b6fc0>, ConstraintRef(package_name='org.jpyinterpreter.user.employee_scheduling.domain', constraint_name='Undesired day for employee'): <timefold.solver.score._score_analysis.ConstraintAnalysis object at 0x17eddc440>, ConstraintRef(package_name='org.jpyinterpreter.user.employee_scheduling.domain', constraint_name='At least 10 hours between 2 shifts'): <timefold.solver.score._score_analysis.ConstraintAnalysis object at 0x17eddc110>, ConstraintRef(package_name='org.jpyinterpreter.user.employee_scheduling.domain', constraint_name='Max one shift per day'): <timefold.solver.score._score_analysis.ConstraintAnalysis object at 0x17eddc200>, ConstraintRef(package_name='org.jpyinterpreter.user.employee_scheduling.domain', constraint_name='Missing required skill'): <timefold.solver.score._score_analysis.ConstraintAnalysis object at 0x17eddc350>, ConstraintRef(package_name='org.jpyinterpreter.user.employee_scheduling.domain', constraint_name='Overlapping shift'): <timefold.solver.score._score_analysis.ConstraintAnalysis object at 0x17eddc380>, ConstraintRef(package_name='org.jpyinterpreter.user.employee_scheduling.domain', constraint_name='Unavailable employee'): <timefold.solver.score._score_analysis.ConstraintAnalysis object at 0x17eddc2f0>}

Desired: I want to know how many overlapping shifts there are, at which impact weight. Pretty printed (see ScoreExplanation docs)

Also MatchAnalysis should have good toString()

print(f'      {match}')

INFO:app:    16 matches: At least 10 hours between 2 shifts = -9600hard/0soft
INFO:app:      <timefold.solver.score._score_analysis.MatchAnalysis object at 0x17731ddc0>
INFO:app:      <timefold.solver.score._score_analysis.MatchAnalysis object at 0x1023597f0>

Probably needs an upstream fix?
