    v24 v25  
    7777   * EdgeKind.SEGMENT becomes the smallest unbreakable EdgeKind (atomic transition) in the algorithm. 
    7878   * (advantage) The number of transitions in the algorithm vastly decrease, generally resulting in a better layout performance. Here is an example for a one line text with 2 segments: 
    79       
    80      ''Old Solution'' 
    81      OPEN_TEXT 
    82      OPEN_PART 
    83      OPEN_LINE 
    84      OPEN_SEGMENT 
    85      ATOM 
    86      CLOSE_SEGMENT 
    87      OPEN_SEGMENT 
    88      ATOM 
    89      CLOSE_SEGMENT 
    90      CLOSE_LINE 
    91      CLOSE_PART 
    92      CLOSE_TEXT 
    93  
    94      ''New Solution'' 
    95      OPEN_TEXT 
    96      OPEN_PART 
    97      OPEN_LINE 
    98      SEGMENT 
    99      SEGMENT 
    100      CLOSE_LINE 
    101      CLOSE_PART 
    102      CLOSE_TEXT 
    103  
     79    * ''Old Solution'' -> OPEN_TEXT -> OPEN_PART -> OPEN_LINE -> OPEN_SEGMENT -> ATOM -> CLOSE_SEGMENT -> OPEN_SEGMENT -> ATOM -> CLOSE_SEGMENT -> CLOSE_LINE -> CLOSE_PART -> CLOSE_TEXT 
     80    * ''New Solution'' -> OPEN_TEXT -> OPEN_PART -> OPEN_LINE -> SEGMENT -> SEGMENT -> CLOSE_LINE -> CLOSE_PART -> CLOSE_TEXT 
    10481   * (drawback) EdgeKind.SEGMENT has to be more complex to handle the following cases, some of which make more sense to a segment as a whole (in the old solution the responsibilities were spread between OPEN_SEGMENT, CLOSE_SEGMENT and ATOM EdgeKinds): 
    10582    * Badness calculation
