31. As of August 2016, the exact run-time complexity of envy-freeness is still unknown. 32. Then the time complexity for this attack is n, requiring n known distinct p / c pairs. 33. The worst case time complexity of Shoup's algorithm has a factor \ sqrt { p }. 34. In the related key setting, the data complexity is 2 33 and the time complexity 2 64. 35. An implementation described by Donald Knuth achieves the time complexity log " n " ) } }. 36. Use of Schreier vectors to perform this requires less storage space and time complexity than storing these g explicitly. 37. The caching and opportunity for good time complexity suggest to me that it could be very robust to expansion. 38. Again one interesting part is that the sample and the time complexity does not depend on \ textstyle n. 39. They also describe collision attack with 2 181 time complexity and 2 64 memory requirement in the same paper. 40. Linear time is the best possible time complexity in situations where the algorithm has to sequentially read its entire input.
