Order of event cost is: C (cospeciation); D (duplication); HS (duplication & host switch); L (loss/sorting); FD (failure to diverge). Solutions of lowest overall cost are highlighted in bolds. The P-value of each randomized test using Random Tip Mapping (RTM) method was indicated, and Asterisk (*) indicate level of significanece of RTM.
