# macop.callbacks.ParetoCheckpoint

Pareto front Checkpoint class implementation

Classes

`ParetoCheckpoint`(_every, _filepath) | Pareto checkpoint is used for loading previous computations and start again after loading checkpoint

class `macop.callbacks.ParetoCheckpoint.``ParetoCheckpoint`(_every, _filepath)

  Pareto checkpoint is used for loading previous computations and start again after loading checkpoint

  `algo`

    {Algorithm} – main algorithm instance reference

  `every`

    {int} – checkpoint frequency used (based on number of evaluations)

  `filepath`

    {str} – file path where checkpoints will be saved

  `load`()

    Load backup lines as population and set algorithm state (population and pareto front) at this backup

  `run`()

    Check if necessary to do backup based on every variable
