QAOA for MaxCut

Hello @ming !

@ming

The results are still four qubit results, and I am trying to change【xtick_labels = list(map(lambda x: format(x, “04b”), xticks))】to【xtick_labels = list(map(lambda x: format(x, “05b”), xticks))】

I checked your script and it seems that the results are compatible with a 5 qubits problem. However, on this line, the variable most_freq_bit_string is being formatted as a length-4 binary string by writing :04b, as Isaac pointed out in a previous post you made:

@ming

print("Most frequently sampled bit string is: {:04b}".format(most_freq_bit_string))

I think you are getting the impression the result is 4 qubits from here. I would suggest as debug exercise to check out in the decimal form and see if makes sense

Another problem I’ve found in you code is this part:

@ming

xticks = range(0, 16)
xtick_labels = list(map(lambda x: format(x, "05b"), xticks))
bins = np.arange(0, 17) - 0.5

The number of ticks is not compatible with the range of your results, since you have 2^5 possible binary string outcomes. Try fixing the range of the bar plot to match the dimension of your problem I am sure this will help to better visualize your results.
