最小解の定矩に぀いお、Seiji Tomitaの衚

 http://www.maroon.dti.ne.jp/fermat/dioph222e.html

の先頭あたりをよく芋るず、

Smallest: Min(A^4 + hB^4)
Search range: 19000<=h<20000, (A,B,C,D)<100000
When h is fourth power, it is excluded from searching.
???: Temporary smallest solution(found by using elliptic curve theory.
For details, see A^4 + hB^4 = C^4 + hD^4 Part 2.)

ず明蚘しおありたす。
぀たり、Seiji Tomitaは敎数解(A,B,C,D)の倧小を{A^4+h*B^4}の倧小で定矩しおいたす。

Seiji Tomitaに報告するずきは、max{A,B,C,D}による最小解□に加えお、(可胜であれば){A^4+h*B^4}による最小解○も報告した方(怜玢範囲をぎりぎりではなく、少し広げる必芁がある)が良いでしょう。

たた、Mathematics Stack Exchange(MSE)サむトに、 A^4+n*B^4=C^4+n*D^4の敎数解に関する質問の回答に、Seiji Tomitaの衚よりも新しい最小解の情報(ただし、n<5000)が公開されおいたす。MSEでは、最小解□ず最小解○は区別されおいたす。
今回確認できた最小解□も既知のものが倚数あるようですが、n>=5000のデヌタは掲茉されおいたせん。最初に、MSEのデヌタを参照した方が良かったかもしれたせん。

らすかるさん
max{x,y,z,w}<4500000の党域調査(結果は同じ)をしおいただき、ありがずうございたす。

毎回、らすかるさんの手を借りるのも申し蚳ないので、らすかるさんのアルゎリズムをGoogle AIモヌドに読み蟌たせお、いく぀かの指瀺を䞎えお、Cプログラムのひな型を䜜成させ、
それを自分で修正しお、なんずか完成させたした。

動䜜確認ずしお、n=2049, max{x,y,z,w}<=10000で実行するず、
   x = 2476, y = 549, z = 3842, w = 231
   x = 4952, y = 1098, z = 7684, w = 462
の個の敎数解を0.5[s]ほどで蚈算できたした。

このCプログラムを自分で䜿甚するのは問題ないず思いたすが、らすかるさんのアルゎリズムに基づくこず(およびスレッド3242のURL)を明蚘した䞊で、GPLv3を付けお公開しおも良いでしょうか

問題がなければ、もう少し修正した埌、この掲瀺板で(他の方も利甚できるように)公開したいず考えおいたす。

8712の最小解は二぀目の方(z=56056)ですね。
・・・ず曞いおから䞍安になったのですが、確か「最小解」は「max{|x|,|y|,|z|,|w|}が最小の解」でしたよね
「匏の倀が最小」ずいう考え方もありたすが・・・

敎数解を゜ヌトするのをさがっお、間違えたした。
「max{|x|,|y|,|z|,|w|}が最小の解」の方が簡単なので、こちらを採甚したす。
(「{x^4+h*y^4}が最小の解」ずいう別の定矩もありたすが、蚈算がやや面倒なので、こちらは䜿いたせん。)

最初の定矩を採甚するず、n=8712のずきの最小解は、
   30668^4+8712*6907^4=56056^4+8712*5939^4 (正)
   3338^4+8712*6209^4=59966^4+8712*1191^4  (誀)
です。

No 3280の"dqde4.c"のC゜ヌスコヌドの修正です。

らすかるさんのアルゎリズムの本質的な修正ではなく、-m 1500000 あたりでの必芁メモリが倧きいので、以䞋のように行を倉曎するず、必芁メモリを少し抑えるこずができたす。n_val*60の定数60は、他のパラメヌタに合わせお、倚少の調敎(増加)が必芁かもしれたせん。

(倉曎前)
long long capacity = (n_val < 500000) ? 5000000 : 300000000;

(倉曎埌)
long long capacity = (n_val < 500000) ? 5000000 : (n_val < 3000000 ? n_val*60 : 300000000);

以降は、この修正を入れた"dqde4.c"を䜿甚したす。
