D.2.3.18 timeStd

Procedure from library general.lib (see general_lib).

Usage:
timeStd(i,d), i ideal, d integer

Return:
std(i) if the standard basis computation finished after d-1 seconds and i otherwhise

Example:
 
LIB "general.lib";
ring r=32003,(a,b,c,d,e),dp;
int n=7;
ideal i=
a^n-b^n,
b^n-c^n,
c^n-d^n,
d^n-e^n,
a^(n-1)*b+b^(n-1)*c+c^(n-1)*d+d^(n-1)*e+e^(n-1)*a;
def i1=timeStd(i,1);
def i2=timeStd(i,20);
listvar();
==> // n                              [0]  int 7
==> // r                              [0]  *ring
==> //      i2                             [0]  ideal (SB), 746 generator(s)
==> //      i1                             [0]  ideal, 5 generator(s)
==> //      i                              [0]  ideal, 5 generator(s)
