QuadraticProgram.binary_var_dict¶

QuadraticProgram.binary_var_dict(keys, name=None, key_format='{}')[fuente]¶

Uses “var_dict” to construct a dictionary of binary variables

Parámetros:

name (str | None) – The name(s) of the variable(s). If it’s None or empty "", the default name, e.g., x0, is used.
key_format (str) – The format used to name/index the variable(s).
keys (int | Sequence) – If keys: int, it is interpreted as the number of variables to construct. Otherwise, the elements of the sequence are converted to strings via “str” and substituted into key_format.

Devuelve:

A dictionary mapping the variable names to variable instances.

Muestra:

QiskitOptimizationError – if the variable name is already taken.
QiskitOptimizationError – if less than one variable instantiation is attempted.
QiskitOptimizationError – if key_format has more than one substitution or a nested substitution.
