```
void addPhaseLifecycleListener(PhaseLifecycleListener<Solution_> phaseLifecycleListener)
```
    Add a PhaseLifecycleListener that is only notified of the phase and the step starting/ending events from this phase (and the solving events too of course).
    To get notified for all phases, use AbstractSolver.addPhaseLifecycleListener(PhaseLifecycleListener) instead.
    
    Parameters:
    
    phaseLifecycleListener - never null
  - removePhaseLifecycleListener
```
void removePhaseLifecycleListener(PhaseLifecycleListener<Solution_> phaseLifecycleListener)
```
    Parameters:
    
    phaseLifecycleListener - never null

  - solve
```
void solve(SolverScope<Solution_> solverScope)
