Chain Break Fraction
I executed some experiments using "sample_qubo" and "num_reads=1000". I realized that 80% of experiments have a "chain_break_fraction" between 1% and 22%. I wonder:
1) what is the maximum "chain_break_fraction" percentage to the "response.first.energy" be considered a valid answer? (zero?)
2) is there some way to remove/ignore, from the response, all the energies (num_reads) with a non-zero chain_break_fraction? (purging the response)
3) is there some way to find the best value for "chain_strength"? (only trying several combinations?)
4) what more can I do to improve the response quality?
Thank you so much.
