class InstanceData​

Instance Data class

The constructor provides type validation and conversion from user's input to valid instance data type.

Attributes​

  • tensor_data(dict[str, numpy.ndarray]) : tensor value of Placheolder. The key is uuid of the corresponding Placheolder.
  • jagged_data(dict[str, list]) : jagged array value of JaggedArray. The key is uuid of the corresponding JaggedArray.
  • fixed_variables(dict[str, dict[tuple[int, ...], float]]) : fixed variable values.
  • indices(dict[str, int]) : value of Element. The attribute is changing in compile process.

__init__ (self, instance_data, fixed_vars, ph_names, indices) -> -​

Parameters​

  • instance_data(dict) : user input instance_data.
  • fixed_vars(dict) : user input fixed_variables.
  • ph_vars(list[name]) : Placeholder list include user defined model. This is used for validation.
  • indices(typ.Optional[dict]) : value of each Elements. Defaults to None.

Raises​

  • ValueError: user's input is invalid.

get_length (self, name, subscripts, axis) -> -​

get_value (self, uuid, subscripts) -> -​

class SubstituteError​

Substitute Error.

This error is raised when the substitute function. This class is inherited from JijModelingTranspilerException.

class VariableMap​

VarialeMap

This class is used to manage the mapping between the label and the index of the decision variable.

Attributes​

  • var_map(dict[str, dict[tuple[int, ...], int]]) : label, subscripts -> index (int)
  • var_num(int) : number of variables
  • integer_bound(dict[str, dict[tuple[int, ...], IntegerBound]]) : bounds of integer decision variables.

add_cont_variable (self, label, subscripts, lower, upper) -> -​

Add an integer variable to the variable map.

add_int_variable (self, label, subscripts, lower, upper) -> -​

Add an integer variable to the variable map.

add_variable (self, label, subscripts) -> int​

Add a variable to the variable map.

Parameters​

  • label(str) : label of the variable
  • subscripts(tuple[int, ...]) : subscripts of the variable

Returns​

  • int : index of the variable in the variable map

from_serializable (data) -> -​

to_serializable (self) -> dict​

Convert to a serializable object.

Returns​

  • dict : serializable object

Examples​

varmap = VariableMap()
varmap.add_variable("x", (0, 0))
varmap.add_variable("x", (0, 1))
varmap.to_serializable()
