The find() function is used to return the index of the first occurrence of an element in a string. We can use it with string slicing to count decimal places in Python.We can slice string using the square brackets ([]). In these brackets, we can specify the start, end, and step ...
We assume that m<22n and the occurrence of non-Clifford unitaries with equal amplitude is not so frequent such that kk1<n2m2(4n−8)m−k. Thus APPROX-CS-DECIDE has a complexity of O(n2m2(4n−8)m), for one particular value of m. Hence, the overall algorithm APPROX-CS-OPT has...
