1a178fb17 | Karim Belabas | Mon, 2 Dec 2019 16:55:51 +0100

lessen bnfinit(,1) shortcomings

1) try to guess precision intelligently (avoid consecuting increases)
2) don't mix t_INT and floating point embeddings in hnfspec.
Still done in hnfadd, harder to fix and probably of lesser importance.

Improves: bnfinit(x^22-2,1)

retune  933a969a: 10 * KC instead of 5 * KC

Rationale: fields with tiny Bach constant would switch too soon. Ex:

x^42-136*x^40+8026*x^38-273576*x^36+6052253*x^34-92411582*x^32+1008728426*x^30-8026067380*x^28+46938257774*x^26-201606584458*x^24+630144063977*x^22-1408482502598*x^20+2195611419763*x^18-2317138276310*x^16+1608865241021*x^14-711986194028*x^12+192461230428*x^10-29991580312*x^8+2504720144*x^6-101501888*x^4+1526784*x^2-128;

(Bach constant = 0.008)

+ add diagnostic for flag = 1 vs 0

933a969aa | Karim Belabas | Tue, 26 Nov 2019 17:50:39 +0100

Buchall_param: restart if Bach constant is low and lots of relations

Rationale: we are probably blocked and do not notice. Improves a lot the
following examples
 bnf=bnfinit(x^4-25*x^2+25,1);
 bnfinit(x^6-x^5-26*x^4+57*x^3+98*x^2-345*x+225,1);
