Boolean Formula Satisfiability - Solving with Minimum Amount of Variables Set to True -


i having trouble coming pseudocode solve boolean satisfiability problem using minimum amount of variables set true.

i have method satisfiable number(h) can call obtain minimum number of variables needed set true in order boolean formula satisfiable. 

find-sat-min(f) { if (not sat(f)) return 0  l = {x | x variable in f}; s = {}; int truecount = 0;  (x in l) {     if (sat(f ^ x) && truecount < satisfiable number(f)) {         s = s u {x};         f = f ^ x;         truecount++;     }     else {         s = s u {not x};         f = f ^ not x;     } }  return s;

}

here's current logic. please let me know if i'm on right track.
