int user_display_solution(void *user)
This function is invoked when the best solution found so far is to be displayed (after heuristics, after the end of the first phase, or the end of the whole algorithm). This can be done using either a text-based format or using the drawgraph process.
|USER_NO_PP||Displaying is done.|
|void *user||IN||Pointer to the user-defined data structure.|
