Description
Heuristic subexponential general-purpose factoring bounds. Here L_X[α,c] = exp((c+o(1))(ln X)^α(ln ln X)^(1−α)); all logarithms in this definition are natural.
Comparison rules
Heuristic subexponential general-purpose factoring bounds. Here L_X[α,c] = exp((c+o(1))(ln X)^α(ln ln X)^(1−α)); all logarithms in this definition are natural. Only compare entries with this cost scale, input domain and computational model. Polynomial and quasi-polynomial expressions without an extracted scalar are not ranked.
