  | calc-contract-cost-flops | Estimate the Flops and Memory requirements only (no tensor contraction)| bool | false |
  +| | | | |
  | | If true, the following info will be added to the AcceleratorBuffer: | | |
  +| | | | |
  | | - `contract-flops`: Flops count. | | |
  +| | | | |
  | | - `max-node-bytes`: Max intermediate tensor size in memory. | | |
  +| | | | |
  | | - `optimizer-elapsed-time-ms`: optimization walltime. | | |

  | bitstring | If provided, the output amplitude/partial state vector associated with | vector<int> | <unused> |
  | | that `bitstring` will be computed. | | |

  | | The length of the input `bitstring` must match the number of qubits. | | |
  | | Non-projected bits (partial state vector) are indicated by `-1` values.| | |

  | | Returned values in the AcceleratorBuffer: | | |

  | | - `amplitude-real`/`amplitude-real-vec`: Real part of the result. | | |

  | | - `amplitude-imag`/`amplitude-imag-vec`: Imaginary part of the result. | | |
