FFT Problem Optimization
Hi —
Recently I submit this solution to a polynomial FFT multiplication problem — POLYMUL.
Even on my computer — this solution runs very slow, and I cannot identify the reason. I'm wondering if anyone can assist in optimizing this solution — there must be something wrong for it to run so slowly.
Thanks in advance, Disguised
