STEP 1.

   If request_(i) > Need_(i) then

      }

STEP3.

   av = av - request_(i);
   call safetty algorithm
      STEP1.   Finish[1...n] = False;
      STEP2.   work = av;
      STEP3.   Find process_(i) if Need_(i) <= work_(i) and Finish_(i) = False
                                       else goto 7;
      STEP4.   work_(i) = work_(i) + Alloc_(i);
      STEP5.   Finish_(i) = True;
      STEP6.   goto 3;
      STEP7.   If Finish[1...n] = True then
                      return (True);
                  Else
                      return (False);
