chain strength with keberos sampler

I am getting an error where I instead of a string of 20638 0's and one value which is 1, i am getting a string of values where more then one value is a 1. In other words I am getting multiple answers instead of 1 answer. I believe that the reason for this is because the keberos hybrid sampler doesn't have a set chain strength. Unfortunately whenever I try to add a chain strength parameter to my keberos solver it says Kerberos() got an unexpected keyword argument 'chain_strength'. How do I set a chain strength for my keberos sampler?

  • Hello,

    There is actually no option to update chain_strength for the KerberosSampler, unfortunately.

    A  ticket has been created to track information on the addition of chain_strength for a Composite that could be used with Kerberos:
    https://github.com/dwavesystems/dwave-system/issues/300

    Unfortunately for the time being it isn't possible with Kerberos, but with a bit of customization it would be possible to do with the dwave-hybrid workflow, using the KerberosSampler code and Kerberos code (KerberosSampler uses Kerberos so this is the important code to help with the workflow) as a starting point.

    I hope this helps!

    Please let us know if you have any questions.
