D.14.4.14 from_boolean_set

Procedure from library polybori.lib (see polybori_lib).

Usage:
from_boolean_set(sb); sb boolean set

Return:
Boolean set sb in the representation of a zdd

Example:
 
LIB "polybori.lib";
==> // ** args must be 1 in     system("install", "bideal",   "ideal",    bid\
   eal2ideal, 4);
ring r=0,(x,y,z),Dp;
poly f=(x+1)*(y+1)*(z+1);
bpoly fb=f;
bset fs=fb;
from_boolean_set(fs);
==> zdd: 
==>  x1(x2(x3+1)+
==>        x3+1)+
==>     x2(x3+1)+
==>        x3+1
==> 
poly g=x*y*z+1;
bpoly gb=g;
bset gs=gb;
from_boolean_set(gs);
==> zdd: 
==>  x1(x2(x3))+1
==> 
ring R=0,(x(1..4)),Dp;
poly h=(x(1)+1)*(x(2)+1)*(x(3)+1)*(x(4)+1);
pyobject hb=boolean_poly(h);
def hs=hb.set();
from_boolean_set(hs);
==> zdd: 
==>  x1(x2(x3(x4+1)+
==>           x4+1)+
==>        x3(x4+1)+
==>           x4+1)+
==>     x2(x3(x4+1)+
