I think I have a better analysis for nim problem which gives .Though it is not a big improvement.I want help to find what is the fault in my method if there is any. So idea is when that ceil(n/k)> , do a single step. And when ceil(n/k)<= .try to reduce ceil value by 1.Remember that N is original number and n is intermediate number.

Each of the two steps cannot take place more than times.Complexity is .

Please find fault in it.
