question: protected void initializePhase ( int w ) { Arrays . fill ( committedWorkers , false ) ; Arrays . fill ( parentWorkerByCommittedJob , - 1 ) ; committedWorkers [ w ] = true ; for ( int j = 0 ; j < dim ; j ++ ) { minSlackValueByJob [ j ] = costMatrix [ w ] [ j ] - labelByWorker [ w ] - labelByJob [ j ] ; minSlackWorkerByJob [ j ] = w ; } }
target:  Initialize the next phase of the algorithm by clearing the committed workers and jobs sets and by initializing the slack arrays to the values corresponding to the specified root worker.
