evaluate(pos)[source]#

Evaluate a given position

Parameters

pos (list) – list of position components (floats)

Returns

fitness value of the given position along with the static data required by ObjectiveInterface

Return type

dict

momentum_eval(pos, weights, m_epochs)[source]#

Redundant implementation as evaluate to satisfy the ObjectiveInterface hooks

Parameters

  • weights (str) – N/A

  • m_epochs (int) – N/A

Returns

a dictionary containing the evaluated fitness value

Return type

dict
