initialize_constraints(constraints, constraint_type)

A tuple of either constraint classes or dictionaries as required by global_methods.

Parameters:

• constraints (dict) – This dictionary of constraint types and their arguments will be converted into the appropriate form for the chosen optimization method. Although the key can be anything, it must represent a dictionary containing:

  • function (str) - must be found in the dictionary and represent a valid

  function name from constraint_types * type - entries depends on constraint_type * args - Inputs into the functions (keys)

• constraint_type (str) – Either ‘dict’ or ‘class’. Changes the constraint to the specified form.

  • ‘dict’: Allowed types, “eq” or “ineq”, eq means must be zero, ineq means it

  must be non-negative * ‘class’: Allowed types, “nonlinear” or “linear”, a keyword argument may also be added for the constraint class

Returns:

new_constraints – A tuple of either constraint classes or dictionaries as required by global optimization methods

Return type:

tuple
