I tried to prove Boneh-Lipton conjecture first with 5.6 sol and then failed. But it told me maybe is not necessary to use this conjecture and then used only ten minutes to return me a proper answer…

We use tools from additive combinatorics to compute the bounds of Coppersmith's method and obtain a series of elegant results. Previously, computing these bounds involved tedious manual calculations or heuristics. Our method is provable and efficient and the code is open-sourced.
