This is a shortcut to get the BackwardSequence of 'var' in the
nth solution. The backward sequence is the list of ranked interval
variables starting from the end of the sequence.
This is a shortcut to get the ForwardSequence of 'var' in the
nth solution. The forward sequence is the list of ranked interval
variables starting from the start of the sequence.

Key actions include adding variables (`IntVar`, `IntervalVar`, `SequenceVar`) and an objective. It provides methods to retrieve solution details: the nth solution (`solution`), solution count (`solution_count`), objective value (`objective_value`), variable values (`Value`, `StartValue`, etc.), sequences (`ForwardSequence`, `BackwardSequence`), and performance metrics like branches, failures, and wall time. The `EnterSearch` indicates the beginning of the search, and the class provides a debug string.\n"]]
