Method wait

dwave/cloud/computation.py:409–444

Wait for the solver to receive a response for a submitted problem. Blocking call that waits for a :class:`Future` object to complete. Args: timeout (float, optional, default=None): Maximum number of seconds to await completion. If None, waits

        Blocking call that waits for a :class:`Future` object to complete.

        Args:
            timeout (float, optional, default=None):
                Maximum number of seconds to await completion. If None, waits
                indefinitely.

        Returns:
            Boolean: True if solver received a response.

        Examples:
            This example creates a solver using the local system's default
            D-Wave Cloud Client configuration file, submits a simple QUBO
            problem to a remote D-Wave resource for 100 samples, and tries
            waiting for 10 seconds for sampling to complete.
