SCIP_Bool SORTTPL_NAME | ( | SCIPsortedvecFind | , |
SORTTPL_NAMEEXT | |||
) |
SCIPsortedvecFind...(): Finds the position at which 'val' is located in the sorted vector by binary search. If the element exists, the method returns TRUE and stores the position of the element in '*pos'. If the element does not exist, the method returns FALSE and stores the position of the element that follows 'val' in the ordering in '*pos', i.e., '*pos' is the position at which 'val' would be inserted. Note that if the element is not found, '*pos' may be equal to len if all existing elements are smaller than 'val'.pointer to store the insert position
