LSStatistics Class¶

class localsolver.LSStatistics¶: Statistics of the search.

Summary¶

Instance methods¶

LSStatistics.get_running_time()¶

Gets the running time in seconds. Note that is the “real” time spent (and not only the CPU or system time). Only allowed in states LSState.PAUSED or LSState.STOPPED.

You can also use the shortcut member running_time

Returns: Running time in seconds
Return type: int

LSStatistics.get_nb_iterations()¶

Gets the number of iterations. Only allowed in states LSState.PAUSED or LSState.STOPPED.

You can also use the shortcut member nb_iterations

Returns: Number of iterations.
Return type: int

LSStatistics.get_nb_moves()¶

Deprecated since version 9.0: This parameter gives an inaccurate view of LocalSolver search.

Only allowed in states LSState.PAUSED or LSState.STOPPED.

Returns: Number of (attempted) moves.
Return type: int

LSStatistics.get_nb_accepted_moves()¶

Deprecated since version 9.0: This parameter gives an inaccurate view of LocalSolver search.

Only allowed in states LSState.PAUSED or LSState.STOPPED.

Returns: Number of accepted moves.
Return type: int

LSStatistics.get_nb_improving_moves()¶

Deprecated since version 9.0: This parameter gives an inaccurate view of LocalSolver search.

Only allowed in states LSState.PAUSED or LSState.STOPPED.

Returns: Number of improving moves.

LSStatistics.get_nb_rejected_moves()¶

Deprecated since version 9.0: This parameter gives an inaccurate view of LocalSolver search.

Only allowed in states LSState.PAUSED or LSState.STOPPED.

Returns: Number of rejected moves.
Return type: int

LSStatistics.get_nb_infeasible_moves()¶

Deprecated since version 9.0: This parameter gives an inaccurate view of LocalSolver search.

Only allowed in states LSState.PAUSED or LSState.STOPPED.

Returns: Number of infeasible moves.
Return type: int

LSStatistics.get_percent_accepted_moves()¶

Deprecated since version 9.0: This parameter gives an inaccurate view of LocalSolver search.

Only allowed in states LSState.PAUSED or LSState.STOPPED.

Returns: Percentage of rejected moves.
Return type: double

LSStatistics.get_percent_infeasible_moves()¶

Deprecated since version 9.0: This parameter gives an inaccurate view of LocalSolver search.

Only allowed in states LSState.PAUSED or LSState.STOPPED.

Returns: Percentage of infeasible moves.
Return type: double
