QEPCAD Timeout

[anirjoshi]

Steps To Reproduce

1. My machine is Mac M2 with the OS Ventura 13.4
2. I already have installed sage with version 10.3 [I believe the same issue exists with 10.4 as well]
   The following program times-out:

var('x')
var('a')
var('y')
var('b')
var('r')

qf = qepcad_formula
F0 = (0 > 0 + 1*x*x*a*a + 1*y*y*b*b + -1*a*a*b*b)
F1 = (0 > 0 + 1*x*x + 1*y*y + -20*x + -20*y + -1*r*r + 200)
F2 = qf.and_(F0,F1)
F3 = qf.and_(F2)
var("tmp")
eliminate_trick = qepcad(qf.exists(tmp,qf.and_(tmp==0,F3)),memcells='1000000000 +L5000')
print(eliminate_trick)

Quantification out of the tmp variable should be pretty easy since this only appears in the constraint tmp==0.

Expected Behavior

A formula without the tmp variable.

Actual Behavior

Just keeps running for a long time.

I this issue is irrelevant to Sage, it should be reported to Qepcad developers.

@maxale , Thank you for the quick response. Since I used Sage software, therefore I thought this is the correct place to report the issue. It would be great if you/someone can point me to the Qepcad developers?
